You are probably right.  Why don't we then just print all symbol names
as we do for units now?  In mathematical contexts variables like in $v$
are printed as Calc currently prints units.

There are variants of the latin alphabet including the same letters
looking a bit different.  People may also want to use these.  I don't
see a reason to exclude anything...oh wait, ok, the characters must be
compatible with all supported language modes, that may be the reason for
the restrictions.
