Please don't permit characters outside the portable subset of
ASCII in zone names.
Comments in text files are non-critical, and if they appear
mangled due to incorrect settings (such as disagreement between
different software layers about what locale is in use), or
due to absence of support in my display font, or if they are
incomprehensible due to my unfamilarity with the language or
character set involved, then it doesn't matter too much. On the
other hand, if I am unable to enter a zone name due to incorrect
settings, or due to missing support in my keyboard driver, or
merely due to personal unfamiliarity with the "foreign" characters
involved, then I won't be able to select the correct zone. This
problem gets worse, for me, as character sets get larger: I might
be able to figure out how to coerce my keyboard driver into
emitting the codes for <latin small letter e with grave>, but I
have very little chance of telling whether two somewhat-similar
glyphs are different renderings of the same Chinese character, or
different characters entirely, and I certainly don't know how to
make my keyboard emit the right codes for them.
This attitude is unfair to people for whom the letters A to Z and
the digits 0 to 9 are foreign, unfamiliar, difficult to read, or
difficult to input. I recognise that unfairness, but do not have
a solution for them.
