I checked with "text-scale-increase" and it did not work. When scale happened, the space_width and column_width of frame did not changed, I need find another way to get monospace font width after scale. But I think we can store the default font face to every xftfont_info and when scale happened, re-caculate the space width of default face. Let me try, thanks for the feedback. 于 2012年04月11日 23:48, Kan-Ru Chen 写道: > [ CC:ed emacs-devel ] > > Hi! > > 黄建忠 writes: > >> Here is a patch to fix double-width issue of CJK fonts when use Xft >> backend , just like some terminal did. > I like you idea to draw glyphs individually when the font is a CJK font. > I didn't realized that when the font changes, XftDrawGlyphs is called > again so we have a chance to examine the font! > > Your patch probably needs some adjust to fit the coding style, but the > approach is great!
