Okay, in next version.  Thanks.

Hmm, there may be problems with this font; I'm told it has bugs.
Maybe the FreeType folks can comment?

Very curious.  I'll try to understand what's going on.

RG> 3) Besides that, I need to fix the spacing value 'p' to 'c' because the
RG> value 'p' will cause delay in several seconds when start-up rxvt.

Again, that's a font bug; mkfontscale tries to work out which fonts
are proportional.  On the other hand, it doesn't yet implement a
heuristic to distinguich monospaced (-m-) from charcell (-c-) fonts.

I guess a suitable heuristic would be to decalare all monospaced fonts
in East-Asian encodings to be charcell.

RG> Would it be merged into next XFree snapshot?

I hope so.

Thanks,
