How to CCLabelTTF::setString unicode characters

How to CCLabelTTF::setString unicode characters
0.0 0


std::string utf8_encode(const std::wstring &wstr)
int size_needed = WideCharToMultiByte(CP_UTF8, 0, &wstr[0], (int)wstr.size(), NULL, 0, NULL, NULL);
std::string strTo( size_needed, 0 );
WideCharToMultiByte (CP_UTF8, 0, &wstr[0], (int)wstr.size(), &strTo[0], size_needed, NULL, NULL);
return strTo;
std::wstring ws(L“我6我”);
std::string str=utf8_encode(ws);
CCLabelTTF* label = CCLabelTTF::labelWithString(str.c_str(), “Arial”, 24);

WideCharToMultiByte is win32 function.

so can’t compile in android gcc enviroment.

then how to convert UTF-8 character string? or,

is cocos2d-x support to unicode TCHAR wchar_t etc…?



cocos2d-x only supports UTF-8.
I’d suggest you record strings in a file which is UTF-8 format.


As far as I understand it, is UTF-8 able to be used with unicode (see an example). Can I use cocos2d-x today to use a emoji such as :sweat_smile:? The main problem is std::string, which doesn’t support it.


UTF-8 is compressed unicode. Cocos and std::string both support UTF-8.

Cocos functions to convert unicode to/from UTF-8 are in ccUTF8.h


But I still can’t show :sweat_smile: within a label. Can you show me a snipped, how to do it?


Cocos has test for unicode strings.

Run cpp-tests.
