[tz] [PROPOSED PATCH 3/3] tzselect now uses UTF-8 if available

[random832 at fastmail.us]

Using a UTF-8 locale won't work if the terminal isn't UTF-8. It should
be piping utf-8 output through iconv -f utf-8 and using the user's
locale.

If the user has a UTF-8 terminal but no UTF-8 locale, that's the user's
problem.
