That would give unprintable characters a width of 1.
Sounds dicey, as we have no way to know the width of a random control
character. On the other hand, it seems like U+00A0 is a longstanding
special case with FreeBSD wcwidth; see:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219800
so perhaps we should make a special case for 0xA0 on FreeBSD.
There are similar issues in ls and numfmt, I suppose.
Goood point on the control chars, but mbswidth() does
special case those, counting them as 0 width.
Anyway this is not an issue for current FreeBSD,
so let's be conservative before the release
and just apply the test fix which is needed in either case
(since wc -L treats all non printable as zero width).
thank you,
