Home / Setting unicode rtf text in rich edit control edit

TODO: move to win32 section

Despite being around for thousands of years, win32 API is poorly documented in many areas.

Today I spent an hour battling a baffling problem with rich edit control.

I was setting rtf-formatted text using WM_SETTEXT message.

In non-unicode build, where text was ansi, it worked and the text showed up nicely formatted.

In unicode build, however, the text wasn’t parsed as rtf and showed verbatim.

An hour of trying various ways to make it work ended with me finding a working work-around: using EM_SETTEXTEX and utf-8 encoded text with CP_UTF8 code-page. I’m using WTL so the code ended up being:

#ifdef UNICODE
 // Don’t know why I have to do this, but SetWindowText() with unicode
 // doesn’t work (rtf codes are not being recognized)
 const char *sUtf = WstrToUtf8(s);
 m_statusMsgEdit.SetTextEx((LPCTSTR)sUtf, ST_DEFAULT, CP_UTF8);

MSDN claims I could have used code-page 1200 for unicode text, but that didn’t work either.

It’s quite possible I’ve botched something somewhere in my code and this work-around isn’t needed but I can hardly think of anything.
