Bundle mkxp with a CJK font like WenQuanYi Micro Hei ?

There are quite a lot rpgmaker games by asian authors, so bundle mkxp with a CJK font should be a good idea. Consider WenQuanYi Micro Hei, it is small (about 4 MB) and contains enough characters for most rpgmaker games.
If not, then consider adding an option to set a custom fallback font in mkxp.conf.

I have considered doing this in the past, but distributing executables bloated up by 4 megs of static data 95% of mkxp users will never require doesn't seem very sound.

It's easy enough to change the bundled font yourself to whatever you want, or to bundle external fonts with your game (see Readme) if you don't want to compile yourself.

Yeah, still I think about adding a option to blindly substitute any unknown fonts with a specified font set in mkxp.conf. I guess this is what "FontSub" is trying to do?

Having a conf entry to change the global fallback font would be a functionality that I'd be okay with.

No. Please read the documentation in mkxp.conf.sample.
