I don't know if this is a bug or just the way Cairo works. On two
different GNU/Linux systems I have built Emacs both --with-cairo and
without. The non-Cairo builds use Xft as the font backend. On those
builds the Ethiopic scripts (Amharic and Tigrinya) in HELLO are
displayed with the Goha-Tibeb Zemen font. In the Cairo builds this font
is not used for these scripts; instead, on one system they are displayed
with a mix of GNU Unifont and mutt-clearlyu, and on the other system,
which lacks these fonts, only hex boxes are displayed. Is there
something about Goha-Tibeb Zemen that is incompatible with Cairo?

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.

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?

Yes, that works, thanks.

Thanks. Please get the latest master and show the results of the
following on both builds:
1. $ emacs -Q -D &
