Description

The cjk fonts occupy too much vertical space for the same fontsize as some other cjk fonts, wasting a lot of precious vertical space.
to illustrate, the below MS Word screenshot has 5 chinese fonts, all fontsizes 12, line spacing at least 0. spacing order is: 新細明體 (default and probably oldest chinese font in MS Windows) = 新一細明體 < 微軟正黑體 (newer chinese font in MS Windows) < 思源黑體香港 (this SHS font) < Noto Sans CJK HK. pls shorten the font height to the same as 新細明體 so it can waste less vertical space.
