Thank you for your advice Burger!
I already knew some of them, but what does "Alt + code" mean?
Example, if the CUSTOM FONT has been set and the LANGUAGE is CP1258, characters are displayed on the screen INPUT (ÄÖÅäöå) correctly(although too big), why the OUTPUT display will still show wrong? I do not get this!
I'm pissed off, because due to this problem, I have to use the old version of SDL, which is "COMPILER ERROR" often, and of course it lacks the newer COMMANDS.
ps. I apologize "compiler phrase" possible misunderstandings produced!
I do not understand English much. ; - /
