Thank you for the nice suggestion. Yes, Hangul characters in "Sarasa Mono" have the same widths. >=20 > Does Sarasa mono looks nice for Japanese, Chinese and Korean > (plus latin)? Yes, I tested "Sarasa Mono SC" and it covers all CJK fonts. The SC variant has Simple Chinese glyph where other languages have their own preferred glyph, but that is same in "Noto Sans Mono SC". Currently, there is no verbatim/literal blocks in the Japanese translation, so I tested with only a short Japanese sentence. I'll post a v2 which uses "Sarasa Mono SC" instead of Unifont. >=20 > If so, I guess it shouldn't be a problem to use it, as the > ./scripts/sphinx-pre-install can be patched to recommend > its install. One minor problem might be that the Sarasa font needs manual download (and install). Thanks, Akira >=20 > Thanks, > Mauro >=20
