For example the invisible letter, you proposed ;-)
I think, it would make sense to have a tiny database of composable
characters, which are actually used, namely in orthography, and in
dictionaries like the Yorouba letters with dot below, the - 35, if I
remember well - unencoded Lithuanian composites, the underline below vowels,
marking long stressed syllables in German dictionaries, etc.
Not every international font needs to comprise any combination which is
possible. Such a database would be a very valuable guideline for font
designers. Can't it be provided by Unicode, of course, not a as part of the
standard?
Best wishes
Gerd
