# supposed to be, but they're only in the comments, the code is all-ascii.

# $translit is a Regexp::Tr mapping Perl wide-chars which are certain greek
# characters (from iso-8859-7) to some latin equivalents.
#
# This is for some greek characters found in otherwise English names, like
# ÂÁÍÊ (0xC2,0xC1,0xCD,0xCA) for BANK in ALPHA.ATH.  That comes out looking
# ok in Gtk or anywhere with good fonts, but for a tty a change to the
# actual intended latin characters is needed to make it printable.
