Yes, as I noted earlier, the character will be fully highlighted if the
first of its two display cells is on the highlighted column, it won't be
highlighted at all if it's the second.

Hm. People might use wide characters:
- in program comments
- in program strings, e.g. in headings to be printed above columns of
results
- in literals used by programs such as Vim, which manipulate text and
have to worry about "wide" vs. "narrow" characters.
In this third case it would probably be possible to use Unicode
constants (coded by means of ASCII text) but I believe that raw text
(including CJK text) would be better in the first two cases.
Also, people certainly do sometimes use wide characters to write _text_
files, and may want their text lines to stay within some bounds, using
this column highlight the way we used to listen to the bell when
computers hadn't yet replaced typewriters.
Best regards,
Tony.
