The petitboot UI looks much nicer in a Unicode locale:
* Items in the language selection submenu use multibyte Unicode
characters. In other locales, they say "Unable to display text in this
locale".
* The combination of TERM=linux with a UTF-8 locale is required to
trigger a special-case workaround in ncurses code[1]. Without
this, line-drawing characters in the menu look like q's.
Turn on wchar support in ncurses, and add a reminder that a UTF-8 locale
should be generated for things to look right.
