The language was Chinese (I should have said characters instead of
scripts, but, alas, sent email can't be edited )=, and the articles
are about calligraphy, so they mention some ancient and variant forms.

(OT comment: That's when I found out that (1) characters in CJK
Extension B, and some in Extension A, normally display as blanks; (2)
there are variant forms used in calligraphy that are not even in CJK
Extension B or compatibility forms; and (3) there are forms that
appear to exist in Unicode but are simply "compatibility" and
apparently I can't rely on their forms being the same as what appears
in the code charts.)
