IupGLText can't handle surrogate pairs ( https://en.wikipedia.org/wiki/UTF-16 ) now.
In windows, a unicode above U+10000 (For example U+1F604 😀 ) will be separated into two WM_CHAR messages. If we got a WM_CHAR with WPARAM between 0xD800 to 0xDBFF , we should wait for another part of surrogate pair, and combine them into one unicode code point. btw, I fix the same issue for imgui . This patch ( https://github.com/ocornut/imgui/pull/2541/commits/fc2dff0ab602e77628a97edd983f03f6f571487a ) is for your reference. -- http://blog.codingnow.com _______________________________________________ Iup-users mailing list Iup-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/iup-users
