Getting "Missing font charsets:" error when starti

After starting to use Unicode instead of “POSIX” locale I started to get this kind of error messages after starting X with “startx”:

[FVWM][FlocaleGetFontSet]: (-misc-fixed-medium-r-semicondensed-*-13-*-*-*-*-*-*, -misc-fixed-medium-r-normal-*-14-*-*-*-*-*-*-*) Missing font charsets:
JISX0208.1983-0, GB2312.1980-0...

I omitted a few items as I had to copy things manually. One of the warnings point to a FvwmScript which does not even use the fonts (“fixed”) listed. But what is the reason for this error message and how to get rid of it?

I’m using now “en_US.UTF-8” as my locale.

I fixed all but one instance of those error messages by adding a “cjk” USE flag to Gentoo Portage and rebuilding the necessary packages. That enables the support for Multi-byte character languages (Chinese, Japanese, Korean).

And the final error message was fixed by specifying a correct font (“none” in my case) for FvwmButtons. No error messages anymore.
