there are several fonts in Creo that are meant to support some specific languages characters set for example when using Russian, Chinese or Japanese characters.
That's great that you already accounted for the users outside of the US. But the world became bigger nowadays. And in parallel, we often deal with Greek letters in the names of our parts.
Looking a consumer devices, even iPhone now supports Unicode 8.0 which allows you to read Russian characters while typing Japanese ones and include a physics question with greek letters, without any problem.
So please standardize on Unicode in the next version of Creo. This would solve all those language specific workarounds because this can all be adapted to standard Unicode.
Yes, Unicode is a real Standard! By settling on this standard, the need for proprietary dealing with different languages vanishes.
