What is reported when you run font-file-at on a character
displayed by that normal variant?

And, the XLFD of 7x13-ISO8859-1.pcf.gz is:
    -misc-fixed-medium-r-normal--13-120-75-75-c-70-iso8859-1
Please run this and check if it is the font you mean by
semicondensed variant?

% xfd -fn -misc-fixed-medium-r-normal--13-120-75-75-c-70-iso8859-1

Also please check if the font shown by this is what you mean
by normal variant:

% xfd -fn -misc-fixed-medium-r-normal--13-120-75-75-c-80-iso8859-1

I still can't reproduce that phenomenon; i.e. the existence
of Japanese fonts affects the font selection.

By the way, I now have a bad feeling that there's no way for
fontconfig to distinguish these fonts:

/usr/share/fonts/X11/misc/7x13.pcf.gz
	-misc-fixed-medium-r-normal--13-120-75-75-c-70-iso10646-1
/usr/share/fonts/X11/misc/8x13.pcf.gz
	-misc-fixed-medium-r-normal--13-120-75-75-c-80-iso10646-1

They differ only in AVERAGE_WIDTH, but fontconfig doesn't
report that value.
