Different font style for different character set

I am a Japanese user and I need a help about customizing font styles.

In Japanese writing system, original character sets like Kanji or Kana and alphabet are mingled together in one document. But in our publishing custom, each uses different font style when showing. For example, while using MS Mincho for Kanji and Kana, alphabet is displayed using Times New Roman, despite the fact that MS Mincho also has alphabetic characters in it!!

The problem is that Firefox for Mobile cannot do this kind of font choosing. As I have added a monospaced Japanese font called "MTLmr3m.ttf" (the default Japanese font in Jelly Bean) to /system/etc/fallback_fonts.xml, Firefox always shows monospaced dirty alphabet of the font set unless otherwise noted in stylesheet.

Of course, other browsers like Browser or Chrome can handle this correctly.

While I love Firefox and I want to read clear Japanese with the new font, it is not tolerable to see the dirty alphabet.

How can I solve this problem?

I solved this problem myself.

It is font.name-list.sans-serif.ja property in about:config that configure the precedence of font family applied to sans-serif style, which is the default font style of Firefox.

My default value of the property was MotoyaLMaru, MotoyaLCedar, Droid Sans Japanese. This means "apply Japanese font to every single character in web pages."

I changed it to Roboto, Droid Sans, MotoyaLMaru, MotoyaLCedar, Droid Sans Japanese, which means "use Roboto or Droid Sans if the character is supported by the font family; otherwise use Japanese font."

And everything works fine now.
