Re: [tz] zic tweak to warn about non-ASCII in filenames

I don't see the digits in there; are they handled separately?

No, because the Theory file does not consider digits to be benign. Because the behavior of a TZ setting like "PST8" is specified by POSIX, it's problematic to use 'zic' to define a zone name like that.

What is the benefit of the parentheses around the string?

I thought it'd help GNU Emacs indent it. But it can be reworded to avoid that; I plan to do that as part of my next proposed patch.
