On GUI frames Emacs takes the width of each character in pixels from the font that is being used. So if you want each Chinese character to take exactly 2 character cells of an ASCII character, you need to find a pair of fonts that satisfy this relation. Because the font used for ASCII varies between users, and the font used for Chinese probably varies as well, I don't think I see how Emacs can solve this problem, because Emacs doesn't understand the significance of each font. > it let all Chinese new users and many old users puzzle a lot, that is the reason my cnfonts package (a Chinese fonts setup utils) get >600 github star. > recent day, we talk about Emacs fonts, so I want to know, is it possible provide a feature in emacs core to solve this problem? Which problem is that? The 2 questions you asked or something else? > The two question is that: How to force set min line-width to a value? What do you mean by "min line-width" here? > Chinese emaser use will use two fonts generally, a Ascii fonts and A Chinese fonts. > Two fonts will use different height to let 1 Chinese Char width = 2 * Ascii char width,  but this set will get other problem: > >      (2)                     Chinese char Height > Ascii char height, > > > The results is that head-line, mode-line and minibuffer's height will shark (change frequently depend Chinese char exist or not). > it looks very very ugly. Did you try to set the line-height text property on the newline of each line?
