It appears to work ok, but is noticeably slower compared to the master branch. I also found the following minor issues: a) On harfbuzz and master branches from "emacs -Q", a machine without the Symbola font does not display the emoji U+1F44B WAVING HAND SIGN (no font available). Babelmap shows that this character is available using the built-in "Segoe UI Symbol" or "Segoe UI Emoji" fonts (or by installing Symbola). b) On the harfbuzz branch from "emacs -Q", the lao U+EC3 LAO VOWEL SIGN AY and U+EC3 LAO VOWEL SIGN O characters are not displayed (no font available). Babelmap shows that this character is available using the built-in "Leelawadee UI" font. I use the following to speed up finding built-in fonts on Windows 10: (pcase-dolist (`(,font-spec . ,targets) '(;; Unicode blocks --------------------------------------- ("Segoe UI Emoji" (#x1f900 . #x1f9ff)) ; Supplemental Symbols and Pictographs ;; Unicode scripts -------------------------------------- ("Segoe UI Symbol" braille mathematical symbol) ("Leelawadee UI" khmer thai lao) ("Nirmala UI" bengali devanagari gujarati kannada malayalam oriya sinhala tamil telugu) ("Microsoft Himalaya" tibetan) ("Myanmar Text" burmese) ("Ebrima" ethiopic) ("Gadugi" canadian-aboriginal cherokee))) (dolist (target targets) (set-fontset-font "fontset-default" target font-spec nil 'prepend))) Perhaps the built in fonts should be added to the default mappings for Windows 10.
