Description Flags
Chinese locale, without ~/.i18n
none
English locale, with "export FC_LANG=zh_CN" in ~/.i18n
none
English locale, with "export PANGO_LANGUAGE=zh_CN" in ~/.i18n none

Description Peng Wu 2016-05-30 09:19:11 UTC 
Recently some Chinese user reports that they use English locale by default,
But still want to use Chinese when reading/writing.

For GNOME 3.x, when use FC_LANG=zh_CN in ~/.i18n, the English character
becomes slightly bolder.
With PANGO_LANGUAGE=zh_CN in ~/.i18n, the English character is the same.

Please evaluate it, thanks!

Sure, screenshots uploaded.
Comment 6 Akira TAGOH 2016-05-31 09:23:57 UTC 
Thanks. hmm, does FC_LANG=en:zh_CN give you the same result?
Comment 7 Peng Wu 2016-05-31 10:28:48 UTC 
Yes, it looks similar.
Comment 8 Akira TAGOH 2016-05-31 10:38:59 UTC 
Then I'd suggest to add English prior to Chinese on fonts-tweak-tool. that should works unless applications uses rich rendering libraries like pango and Qt which supports the sort of the font sets.
this is because pango takes care of ascii characters separately and requests an English font unless you explicitly override that behavior in the font configuration.
Comment 9 Peng Wu 2016-06-01 04:47:29 UTC 
Thanks, it is a good solution for Chinese locale by adding English first.
Comment 10 Akira TAGOH 2016-06-01 04:53:10 UTC 
Okay, I'll close this then. thanks.
