C++ :: Decoding Unicode Characters To String
Jan 6, 2013
I'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 ..?

I'm trying to have a button marked by the sqrt sign, '√'.
I wrote below code and typed that sign by holding down "alt" and typing 251 using numpad. But result is the question mark instead of sqrt mark!
My machine is Windows 7 x86 and IDE is visual studio 2012.
#include <GUI.h>
using namespace Graph_lib;
//---------------------------------
class Test : public Window {
public:
Test(Point, int, int, const string&);

I want to print out unicode characters. But I want to do this using the key ids. Example:

std::cout << ('124'); //I would like this to output '|'
}

I need to read Unicode characters from a file. The only thing I need to do from them is to extract their Unicode number.
For example if file has u I need to extract its corresponding Unicode number.

I 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.

How 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.

I'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?

I am using Visual Studio 2008. I just wonder if there are any library function in Windows SDK or MFC, or from third-parties, that can convert a UTF-8 string into Windows Unicode string(used in CString object).
Can MultiByteToWideChar or ATL String conversion macro like A2W to the conversion?

I'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"?

Im supposed to find the common characters between two string characters, assuming that the user wont input duplicate letters like ddog. When I run my code I get an output of a question mark upside down. Here is my code with comments on what each part is supposed to do
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(){
char str1[20], str2[20],remp = '
