C++ :: Printing Unicode Characters With Key IDs
Feb 5, 2013I want to print out unicode characters. But I want to do this using the key ids. Example:
int main()
{
std::cout << ('124'); //I would like this to output '|'

C++ :: Printing Chinese / Unicode Characters To Line Printer Using WritePrinter Method?
Jul 10, 2013I'm trying to print Chinese/unicode characters to a line printer(EPSON LQ-2090) using the writePrinter method in c++.
ANSI characters print fine, but when I throw the buffer of widechar Chinese characters at it, they come out like garbage/ANSI chars.
while debuging string shows chinese characters but in memory it shows ANSI characters not chinese and these ANSI characters are get printed on printer.
Note that if I change the DocInfo datatype parameter to "TEXT" instead of "RAW" then also the Chinese characters donot print.
Is there a way to get Chinese or unicode characters to print correctly?
C/C++ :: Printing Out Unicode Hex As Chars
Feb 10, 2014I'm writing a school assignment that writes/reads user input into and out of a binary file.
I've gotten the write part to work, but now I need to be able to read that file back in and display it as a string.
I think I should be using fread() and read my file into an array of int's right? But when I try printing out that array I get a whole bunch of numbers that don't match the hex code in my file.
How do I read in a binary file and print it out as a string?

C++ :: Decoding Unicode Characters To String
Jan 6, 2013I'm having some problems in receiving fileNames from Server to Client(C++) in Mac OS X. I send a serialized object , which has a char pointer with the fileName or sometimes a string object, when i receive it in the client, it seems to be having %F6 or %E9 ,etc . This issue don't arise in Windows OS though, even thought it's the same code. Is there anyway decoding these '%' characters back to their original form in Mac OS & Linux ..?
Fex characters i got into problems with : ǡ ȅ ȉ
It would be difficult to change the code in server, so if there's a way decoding the characters back to its original form, it would be easier.I'm using Boost Library for Serialization and i'm just looking for ways to decode %F6 back to ȅ in C++, like if some library is available ..?
C++ :: How To Send UNICODE Characters To Serial Port
Jul 17, 2013I am trying to write data in Russian language to the serial (RS-232) port. My display device is already set to that character code page.
But output on the device is not exactly what I require.
My code snippet is like this below
CString pBuffer = L"английский"; //Russian Language
LPBYTE pByte = new BYTE[pBuffer.GetLength() + 1];
memcpy(pByte, (VOID*)LPCTSTR(pBuffer), pBuffer.GetLength());
long nBuffer=pBuffer.GetLength()+1;
DWORD dwWritten=0;
WriteFile(pHandle , pByte, nBuffer ,&dwWritten , NULL);
pHandle is a valid handle.
C++ :: Open File Named In Unicode Characters
Sep 22, 2012How to open a file which its name is unicode letters ? usually :
Code:
basic_ifstream<wchar_t> src("source.txt");
Work well to read file with unicode content not filename, so that example doesn't work :
Code:
basic_ifstream<wchar_t> src(L"source.txt");
Also, I have seen some alternatives for using open function but it doesn't work as well.
Code:
basic_ifstream<wchar_t> src;
src.open(L"source.txt");
I use g++ compiler.

Visual C++ :: Getting Unicode From API DLL Using Non-Unicode Program
Aug 29, 2013I have some code that was compiled without Unicode turned on in the Preprocessor Definitions. I need to access an API that had Unicode turned on in the Preprocessor Definitions (I believe that it is on by default for DLL's) .
I need to call a function in the DLL that requires a structure like:
struct READERINFO {
TCHAR serial[32];
TCHAR altSerial[32];
TCHAR name[32];
TCHAR fccId[48];
TCHAR hwVersion[16];
int swVerMajor;
int swVerMinor;
char devBuild;
};
It returns some information in the structure some of it is Unicode based however the program that is calling it is not Unicode. The preprocessors are not turned on because if they were there would be a lot of things to change in this code. The code is old code that I inherited and now I must interface to some new devices.
I declare my structure as :
READERINFO info; Then I call the function in the DLL which looks like: ApiGetReaderInfo(hAPI, &info, sizeof(into));
Which is defined as:
ApiGetReaderInfo(HANDLE hApi,
Struct READERINFO * ri,
DWORD riSize);
Parameters:
hApiHandle to valid Api object instance
riPointer to the READERINFO structure.
riSizeSize of ri structure in bytes. Usually: sizeof(struct READERINFO).
When I call it from my program that does not have UNICODE defined in the Pre-Processors I get :
Characters like : ÌÌÌÌÌ in the TCHAR fields and invalid numbers in the integer fields.
int ModuleVersion(HANDLE hApi) {
struct READERINFO info;
ApiGetReaderInfo(hApi, &info, sizeof(info));
[Code] ....
When I call it from my program that has some sample code just for this and has the UNICODE defined in the Preprocessors it works just fine. how I can call this from my old code and get the correct information. I have already tried to do the follow without success:
int ModuleVersion(HANDLE hApi) {
#define UNICODE
struct READERINFO info;
#undef UNICODE
ApiGetReaderInfo(hApi, &info, sizeof(info));

C :: Reading And Printing In A Specific Format Strings Of Characters And Integers
Feb 23, 2015I have been skimming and searching but dont know how to word the search just right to find what I need to know. I have written simple stuff with the support of tutorials like weight conversion or loops counting up to a set number. Nothing amazing. The other day I found out how to input and print a string rather than a single text character which i though was bad ass. I even got it to read multiple strings on a single line and found a way to read multiple lines. I can even format it to read both integers and characters on the same line as long as I know the predefined format.
On to my question... How do I read multiple lines with both carecters and integers. for instance:
nissan 1996
toyota 1998
or more comples like
nissan gtr 1996
toyota markii 1998
I want to use
int year;
char make[10]; maybe need to use char make[10][10]; for an array i would guess.
char model[10]; optional for the extra data
but reproduce what i read in a different order. say...
1996 nissan
1998 toyota
vice the original format.
this is what I have tried.
Code: scanf("%s %s", &make,&year);
//The way I seen to read multiple lines was on here
scanf("%[^/t]", %make);
But this wont let me separate the two into two differnet definded data types. Let alone use printf to display them in reverse order.

C++ :: Is UNICODE Enabled By Default In VC++ Express
Feb 25, 2014For example if using FindFirstFile(...) it assumes your passing LCPWSTR and not LPCSTR.
I know I can use FindFirstFileA or FindFirstFileW so what is point of default if always UNICODE.
Which brings to my second question. If I say
FindFirstFile("C:", &fdat);
I get error cannot convert parameter 1 from 'const char [7]' to 'LPCWSTR'
I could say WCHAR fName = "C:"; and pass this variable instead. However is there a way to cast "C:" on-the-fly to LPCWSTR, I tried,
FindFirstFile((LCPWSTR)"C:", &fdat);
But it outputs a stream of LONGs to the console instead of filenames.
C++ :: Saving Unicode Data To TXT File

C++ :: Unicode Support For Windows Renaming API?
Nov 7, 2013I had a file which has name like SIRAO.wav Since this file name has special unicode character all file API's are failed.
I would like to rename this file using Windows API. How can achieve this?
std::string filename variable hold this value as SIRÃO.wav.
I try to read the file using file API after perform a conversion.
Code:
const int utf16_length = MultiByteToWideChar(CP_UTF8,0,filename.data(),filename.length(),NULL,0);
std::wstring utf16;
utf16.resize(utf16_length);
MultiByteToWideChar(CP_UTF8,0,filename.data(),filename.length(),&utf16[0],utf16.length());
const wchar_t *name = utf16.c_str();
rename the file with unicode character?

Visual C++ :: Whether 0xFFFF Is A Valid Unicode Character
Dec 22, 2013I just wonder whether 0xFFFF is a valid Unicode character.
When I using the following code:
CStringW strTempW;
CString strTemp1;
INT_PTR nLen;
strTempW.Format(L"%c", 0xFFFF);
nLen = strTempW.GetLength();
strTemp1 += strTempW;
nLen = strTemp1.GetLength();
After executing the first codeline strTempW.Format(L"%c", 0xFFFF), I will get strTempW of length 1, but cannot see it first character in Visual Studio watch window.
After executing the codelilne strTemp1 += strTempW, I will get strTemp1 of length 0.
Whether 0xFFFF is taken as a valid Unicode or not?

Visual C++ :: Convert Unicode (UTF-16) Functions To Ansi (UTF-8)
Nov 20, 2012Working in Win32 console app (VS 2010) I have been trying to convert several Unicode (UTF-16) C++ functions to Ansi C (UTF-8). The test app includes two tokenizer classes, each of which work perfectly well in their respective environments, CTokA and CTokW (UTF-8 and UTF-16).
A problem arises when I attempt to run the UTF-8 functions when the Character Set properties is set to 'Use Unicode Character Set' in that std::string manipulations do not perform as expected, e.g.,
printf("start
");
gets reproduced as
printf("start
");══════════ ²²²²
Attempting to null terminate the string where it is supposed to end simply results in a space in that position and the garbage end persists, e.g.,
printf("sta t
");══════════ ²²²²
Code:
sline[11] = 0x0000;
If I attempt to change the Character Set property to 'Use Multibyte Character Set' or 'Not Set', the app will not compile and hundreds of errors occur. Of course, I can eliminate all of the UTF-16 code, but it strikes me that it should not be necessary. Perhaps if M$ made everything UTF-16 without all of the necessary decorations like 'L' and '_T(', life would be much simpler. Unfortunately, I have a very extensive UTF-8 app under 10 years of development that works quite well, but my UTF-16 (Unicode) conversion doesnt work as well because of the mixing of pointers (I think), so I have had to revert much of the code back to UTF-8. (All of which has nothing to do with my question but is simply psychotheraputic for me to ventilate on.)
My question is this: Can UTF-8 and UTF-16 code coexist in a single Win32 console app?

Mar 20, 2015I'm transferring a unicode string from one program to another with UTF-8 encoding.
Program that is sending:
Code:
// Convert path
std::wstring_convert<std::codecvt_utf8<wchar_t>> utf8_converter;
CString arg = L" /PATH="" + CString(utf8_converter.to_bytes(path).c_str()) + L""";
Program that is retrieving:
Code:
// Restore original path
std::wstring_convert<std::codecvt_utf8<wchar_t>> utf8_converter;
std::wstring path = utf8_converter.from_bytes( argument );
Everything has worked fine, until running on a Japanese edition of Windows.
The "byte path" then looks something like "C:¥Users¥d✝?✝a ,?¥AppData¥Local¥Temp¥file.txt".
"from_bytes()" will throw an std::range_error exception "bad conversion".
The program works fine when working with Japenese writing inside paths in the English edition.
What could be causing the "bad conversion"?
C++ :: Output Unicode Number If Extract A Character Off A Console Or Out Of A File
Oct 31, 2014How do I output a Unicode number if I extract a character off a console or out of a file.
If I do the below, I use the Unicode number to show a character. The below shows me 25² .

mystring.append(1,b);
How do you go back the other way? If I extract the 25 and the ² separately, how do I get the unicode number for ² ?
