:ui unicode

Description   unfold

This module extends Doom's ability to display non-English unicode. It is primarily useful for non-English Emacs users, for whom Doom's built-in unicode support in insufficient.

This module relies on the unicode-fonts package. It tries to setup the default emacs fontset to cover as many unicode glyphs as possible by scanning all available glyphs from all available fonts.

When this module is enabled:

  • Emacs will prefer to use the doom-unicode-font font to display non-latin glyphs if it provides coverage for them.
  • The first time you run Emacs a unicode cache will be generated this will take a while!
  • The cache will be regenerated every time Emacs is made aware of new fonts or you change the font configuration e.g. by modifying doom-unicode-font.
  • The cache will be stored and should not be regenerated unless font-related configuration or the versions of relevant packages changes.

TODO Configuration

󱌣 This module's configuration documentation is incomplete. Complete it?

The first font that will be analyzed to see if it contains the glyphs of non-latin characters will be doom-unicode-font:

;; in $DOOMDIR/config.el
(setq doom-unicode-font (font-spec :family "Fira Mono"))

If your doom-font provides good unicode coverage use:

;; in $DOOMDIR/config.el
(setq doom-unicode-font doom-font)

If your font does not provide some glyphs, this package will try its best to find another font that does.

Getting fonts with good coverage

A list of fonts with good unicode coverage can be found on the page of the unicode-fonts package.

Advanced configuration

Consult the unicode-fonts package documentation for a description of more advanced configuration. The configuration should be placed, as usual, in $DOOMDIR/config.el wrapped in an (after! unicode-fonts) block. The variable unicode-fonts-blocks contains a list of all unicode block names and their character ranges. The default fonts to search for glyphs are in the variable unicode-fonts-block-font-mapping.

If you want to use the font Symbola for Miscellaneous Symbols by default use:

;; in $DOOMDIR/config.el
(after! unicode-fonts
  (push "Symbola" (cadr (assoc "Miscellaneous Symbols" unicode-fonts-block-font-mapping))))

If you want to redefine several blocks an efficient way would be:

(after! unicode-fonts
  (dolist (unicode-block '("Mathematical Alphanumeric Symbols"
                           "Mathematical Operators"
                           "Miscellaneous Mathematical Symbols-A"
                           "Miscellaneous Mathematical Symbols-B"
                           "Miscellaneous Symbols"
                           "Miscellaneous Symbols and Arrows"
                           "Miscellaneous Symbols and Pictographs"))
      (push "DejaVu Math TeX Gyre" (cadr (assoc unicode-block unicode-fonts-block-font-mapping)))))

You can find a list of fonts available to emacs using M-x counsel-fonts.

Troubleshooting

TODO Emacs daemon mode (#3328)

This module may fail to setup fonts when emacs is run in a daemon session.

This is a known issue with an unidentified cause. See rolandwalker/unicode-fonts#36. A workaround is to delete your unicode-fonts cache and restart Emacs:

# $EMACSDIR == where you cloned Doom Emacs
rm -f $EMACSDIR/.local/cache/pcache/unicode-fonts
