I'm not sure how much such an information on what characters can be used will be
used, but it seems a logical complement to things such as the 'maximum size'
information, etc.

>From past experience I recall mostly two cases:
- Preventing the use of forbiden characters in the translation of paths and
filenames (while I'm not a fan of localizing paths, sometimes it's simply
required by the translation customer).
- Using half-width Katakana in Japanese (for translation of LCD panels with
limited font resources).
