As stated above, I think the negative expand is forbidden for monospace
or charcell fonts, according to X spec. So, rendering engines should
also use special placement algorithm to combine the characters, like
what has been done in xterm or emacs.
The exception is for proportional fonts, where negative expand is allowed.
Right?

Yeah, that's right.
