--- Comment #6 from Thorsten Glaser <tg at mirbsd dot de> ---
I’ve filed https://sourceware.org/bugzilla/show_bug.cgi?id=21750 noting _all_
differences from Markus Kuhn’s xterm code (updated for Unicode 10) to the
current glibc localedata.

For this particular problem, the fix is easy (interestingly enough, I had a
similar bug in MirBSD when redoing the wcwidth code): read EastAsianWidth
before, not after, UnicodeData, so the NSM bidi class overrides the width set
by the former.
