HarfBuzz is in. It was the normal repository installation.
Cc: 44528@debbugs.gnu.org From: Fr Ml <fr_ml@t-online.de> Date: Thu, 12 Nov 2020 08:14:30 +0100 in the INSTALL instruction of Emacs we read: (On GNU and Unix systems, Emacs needs the optional libraries "m17n-db", "libm17n-flt", "libotf" to correctly display such complex scripts as Indic and Khmer, and also for scripts that require Arabic shaping support (Arabic and Farsi).) But I noticed that libm17n-flt isn't installed and it's not a package in the repository of Archlinux . I didn't need to install it before. Can it be the problem? Or is it included in the other packages (m17n-db, libotf)?This text is outdated: we nowadays prefer HarfBuzz, if available, as our shaping engine. Is your build using HarfBuzz? You can tell by looking at the value of the variable 'system-configuration-features'. If your build doesn't use HarfBuzz, I suggest to install one that does.
