Have you tried entering the text in the program itself using a Textbox
widget? You can also try using literal UTF-8 code units in your program,
like this:
AG_TextMsg(AG_MSG_INFO,
"\xE6\xB1\x89\xE8\xAF\xAD\x2F"
"\xE6\xBC\xA2\xE8\xAA\x9E\x0A");
I've obtained the sequences from: http://rishida.net/tools/conversion/;
this renders correctly using HAN NOM B.ttf, but not under MSYH.ttf.
Agar calls Freetype to render text so you probably won't find anything
relevant to this issue in the Agar code. Agar simply converts the strings
from UTF-8 to UCS-4 and passes them to Freetype as-is.
