Addressed an issue with Japanese language display.

[Qsan-jp]

Japanese hiragana and katakana assigned gothic fonts.
Sazanami-goothic.ttf from U+3040 to U+30FF.

I coped with the kanji used in Japanese which can not be displayed wich can not be displayed with Firefly font.

Thank you for helping with this. Have you verified these changes in either the emulator or a real Tx for both color and monochrome screens? Also, how did you choose the characters to display in the list? I don't see that such a large list is maintainable so I'd prefer to find an alternative to it.

I tested with T8SG v2 plus and emulator.

I heard that there are characters that can not be displayed in Japanese on SNS, and I investigated.
As more letters were expected than I expected, I made a list as below.

1. Make a BDF file of a font to be used as a base and a font to be completed.
   I used fontoforge for this work. https://fontforge.github.io/

2. Extract character code of registered font with grep.
   Extract the row containing ENCODING.

3. Check the difference between the two extraction results in DIFF.
   Lines that contain only the font to be complemented will be the not be displayd character code.

4. Mold a list of character codes and apply to config.

I think that it is realistic to replace the list in the above steps when modifying to the font.

Sorry for bumping this over a year later, but from what I'm seeing build_bdf.py will only output a single glyph for each character right? (I haven't tested it yet, so that's a genuine question)

If so, you could just use the full {"start": "0x4e00", "end": "0x9fff", "ignore_ascent": true} range for both fonts. (ensure that the old Chinese/kanji font is listed before sazanami mincho so it will be used first)

Also, I noticed you accidentally set size 12 for 18bold.
