Well it has worked for quite some time already.

Yes, I and i name the same file. No, I with two dots above it and I with
one dot do not, these are different characters.

No, they do not.

Naming is not language specific, it is alphabet specific only.
Various languages may have various alphabets. I would of course
prefer if we all just used the Latin alphabet plain, as it is used
in English, but there is no problem at all with the capitalization
for its variations. So there is no problem storing the file case
information the right way. Then if you want to store some caseless
hieroglyphs you can do it by just leaving the case information
blank (e.g. in DPS you have up to 255 bytes for text and as many
bits for the corresponding case data).

Language processing is something else and has nothing to do with names.
Similar to the way we deal with a persons name, we do not translate
it but we do spell it correctly whenever the alphabet we use would
allow it.

There is no ambiguity at all in using the Latin alphabet. If one chooses
to introduce one he has to live with it. Your example is not related to
how we store and process case information.

Like it or not file systems deal with files and files are named and the
names are for human consumption to a great part. So the way the names
are stored and searched for belongs there, together with the alphabet
rules which apply to reading/writing these names.
