Re: Cannot paste unicode <0221>, <0234> - <024f>

Probably worth checking if BROKEN_WCWIDTH is already defined in config.h
and if not what happens if you define it.  It has no effect unless
one of __STDC_ISO_10646__ or __APPLE__ is also defined.

An other option is --enable-unicode9, but you'll need the appropriate
header and library support for that to work.

You might want to confirm also if it actually is wcwidth() rather than
iswprint() by hacking zle_refresh.c e.g. the following (untested).  This
might be a plausible patch, actually --- if iswprint() succeeds,
presumably the printing width actually is positive (combining characters
are handled as a special case afterwards).
