As we're on the topic of strange font appearance in Xara:

Another phenomenon is that with *some* fonts that i know to not be corrupt or anything that have alternate characters included ( like an additional "e" letter version with a swoosh or similar - some of LHF fonts come with those) those alternate characters don't show up when typing them (LHF mostly ALT + 4 numbers on the right side of the keyboard), just an empty box.

Why could that be ?
