I was testing a localization by "AceLocale-3.0". I am polish and was testing a few strings in InterfaceOptionsFrame. It turns out that WoW cannot correctly display polish characters and shows them as question marks "?". I read that strings used for localization in different languages should be represented as a sequence of escaped codes in Unicode, e.g. the letter "ż" is coded as a sequence of two following bytes \197\188 (or \xC5 \xBC); link to Unicodes. I have done it but WoW still does not correctly recognise characters in my language.
Any idea what I should do? Does WoW use different code pages when I change text to French?
