Goha-Tibeb Zemen does not have glyphs for ASCII printables that the ftcr font backend relies on computing minimum/average/space width when opening the font. The patch below should simulate the Xft behavior.

The patch below should simulate the Xft behavior. Thanks. I rebuilt Emacs --with-cairo with this patch but the Ethiopic scripts in HELLO are still not displayed with Goha-Tibeb Zemen but also not with the same fonts as before: now they are uniformly displayed with -Misc-Misc Fixed Wide-normal-normal-normal-ja-13-*-*-*-c-120-iso10646-1 Is this the intended result of the patch?

The patch enables us to use the Goha-Tibeb Zemen font on cairo build. If you manually specify the font for Ethiopic characters, then they should be displayed with the font. (let ((script 'ethiopic) (coverage)) (map-char-table #'(lambda (range val) (when (eq val script) (if (consp range) (setq range (cons (car range) (cdr range)))) (push range coverage))) char-script-table) (dolist (range coverage) (set-fontset-font t range (font-spec :family "Goha-Tibeb Zemen")))) Whether it is selected automatically in the default setting is another problem and depends on several factors. What are the outputs of the ldd command for both non-cairo and cairo builds? YAMAMOTO Mitsuharu mituharu@math.s.chiba-u.ac.jp ^ permalink raw reply [flat|nested] 9+ messages in thread
