Accented characters are not converted to uppercase properly
This can happen if you are using Western fonts to display East European languages such as Polish, Lithuanian and Russian. While these fonts usually contain all the required characters, they often do not have the proper lowercase/uppercase encoding for the languages they are supposed to be used for.
What then happens is that accented characters are not uppercased at all, as can be seen in the example below, where the first letter of Wednesday in Polish remain in lowercase, although the token used was [DDDD].
The solution is to create a Capitalization Set that explicitely tells Q++ how to capitalize these problematic characters, and then assign that set to the Capitalization Options of any Language that requires it.
