Not sure if you are doing it or not, but CJK dual-width fonts need
to be treated as monospace, just not metric forced to the maximum
width. (If you want to metric force based on wcwidth() data, that 
would be OK, though a little tricky, but I'm not sure there is a

The reason for this is that these fonts are used in the contexts 
where monospace fonts are used - terminals and text editors.
Most terminal emulators and software that formats text for 
fixed width display properly understand double-char-cell characters
