If fc-match command bundled in fontconfig is invoked with monospace
on ja_JP.UTF-8 locale, "HG-GothicB-Sun" font was displayed as best
much font until nv_b48.
===
% ./fc-match monospace
hggbsun.ttf: "HG-GothicB-Sun" "Regular"
===
However, "Lucida Sans Typewriter" is displayed after b49. 
===
% ./fc-match monospace
LucidaTypewriterR13.pcf: "Lucida Sans Typewriter" "Medium"
===
If --sort option is used, it works fine. So it looks that
FcFontSort works fine but FcFontMatch doesn't. 

I encountered that Japanese characters in some area are rendered by non-Japanese 
fonts with thunderbird or firefox on b49. I think that it is caused by this 
issue because this problem doesn't occur if the following code in 
src/fcmatch.c is commented out or workaround applied.
===
/*
            if ( ls )
            {
                FcValue patLang;

                for (i = 0;
                     FcPatternGet (p, FC_LANG, i, &patLang) == FcResultMatch;
                     i++)
                        ;
                if ( FcPatternGet ( p, FC_LANG, i-1, &patLang) == FcResultMatch
)
                    score[MATCH_LANG_INDEX] = FcHidePoorLangs ( &patLang, ls );
                FcLangSetDestroy ( ls );
            }
*/

Comment out the following with using "<!--" and "-->" in fonts.conf.
