There is no requirement that any given font make all characters distinguishable.
Many characters are almost always indistinguishable anyhow (A vs. Alpha vs.
Cyrillic A); many may be indistinguishable, as Latin alpha vs. Greek alpha,
or even Latin a vs. Latin alpha (which means the font is not usable for IPA,
but that's allowed). The Last Resort font makes all Greek letters
indistinguishable, all Cyrillic letters indistinguishable, etc. etc.

Such a thing would be highly font-dependent and variable.
