I'm a bit confused (encoding issues always confuse me). If we only
care about the width of the string for display purposes, doesn't this
(also) depend on the encoding used by the console / terminal? How does
that actually work: if you have a UTF-8 encoded file, and you 'cat' it
to a terminal with LC_ALL=iso_8859_1 ... ?
