While I don't really have an opinion on the matter aside from the biases
of growing up in the US, one non-trivial issue with Unicode store paths
and package names which hasn't been mentioned is that of Unicode
equivalence[1], particularly homographs[2]. For example U+0061 and U+0430
(the Latin and Cyrillic small letter "a", respectively) are often visually
identical but programmatically distinct. If not handled well, it could
lead to untypable package or store names by virtue of the user having to
guess which Unicode code point(s) is/are the correct one(s) for a certain
visual glyph.
