Godot's built-in font has no Japanese, so kanji in song names showed as boxes. The theme now sets Godot's own Open Sans SemiBold as its default font, with Noto Sans JP Medium as fallback. The Noto file's line metrics are set to Open Sans's, so line heights stay the same and every other screen is pixel-identical; fonts/README.md explains how to redo it. Search and Sync move right to where the Statistics button was.
Fonts
The theme's default font (themes/main_theme.tres) is OpenSans-SemiBold.woff2, the
font Godot uses when a project sets none, saved from Godot so the game looks the same.
Text it has no letters for, such as Japanese, falls back to NotoSansJP-Medium.otf.
Both are under the SIL Open Font License, see OpenSans-LICENSE.txt and
NotoSansJP-LICENSE.txt.
NotoSansJP-Medium.otf is the Medium weight from
noto-cjk, changed in
one way: its line metrics (hhea ascent and descent) are set to Open Sans's. Godot makes
every line as tall as the tallest font in the fallback chain, so with Noto's own, taller
metrics all text in the game would move down and rows would grow, even without any
Japanese on screen. The glyphs are unchanged. To update the font, download it again and
set the metrics with fontTools:
from fontTools.ttLib import TTFont
reference = TTFont("OpenSans-SemiBold.woff2") # needs the brotli package
noto = TTFont("NotoSansJP-Medium.otf")
scale = noto["head"].unitsPerEm / reference["head"].unitsPerEm
noto["hhea"].ascent = round(reference["hhea"].ascent * scale)
noto["hhea"].descent = round(reference["hhea"].descent * scale)
noto["hhea"].lineGap = 0
noto.save("NotoSansJP-Medium.otf")
tests/integration/test_theme.gd checks that Japanese has a font and that the line
height is still Godot's.
