Quickstart
-
Make sure you have installed
font-utils,ucs-utilsandlist-utils. -
Download the
unicode-fonts.elfile, and put it somewhere Emacs can find it, e.g.~/.emacs.d/unicode-fonts. -
Remove Unifont from your system.
-
Install these fonts

Add the following to your
.emacsfile:(add-to-list 'load-path "~/.emacs.d/unicode-fonts/") (require 'unicode-fonts) (unicode-fonts-setup)

Overview
Emacs maintains font mappings on a per-glyph basis, meaning that multiple fonts are used at the same time (transparently) to display any character for which you have a font. Furthermore, Emacs does this out of the box.
However, font mappings via fontsets are a bit difficult to configure. In addition, the default setup does not always pick the most legible fonts. As the manual warns, the choice of font actually displayed for a non-ASCII character is "somewhat random".
The Unicode standard provides a way to organize font mappings: it divides character ranges into logical groups called "blocks". This library configures Emacs in a Unicode-friendly way by providing mappings from
each Unicode block ---to---> a font with good coverage
and makes the settings available via the customization interface.
This library provides font mappings for 233 of the 255 blocks in the Unicode 8.0 standard which are public and have displayable characters. It assumes that 6 Latin blocks are covered by the default font. 16/255 blocks are not mapped to any known font.
To use unicode-fonts, place the unicode-fonts.el file somewhere
Emacs can find it, and add the following to your ~/.emacs file:
(require 'unicode-fonts)
(unicode-fonts-setup)See important notes about startup speed below.
Minimum Useful Fonts
To gain any benefit from the library, you must have fonts with good Unicode support installed on your system. If you are running a recent version of OS X or Microsoft Windows, you already own some good multi-lingual fonts, though you would do very well to download and install the six items below:
From https://dejavu-fonts.github.io/Download.html
DejaVu Sans, DejaVu Sans Mono
From http://www.quivira-font.com/downloads.php
Quivira
From https://dn-works.com/wp-content/uploads/2020/UFAS-Fonts/Symbola.zip
Symbola
From http://www.google.com/get/noto/
Noto Sans, Noto Sans Symbols
It is also recommended to remove GNU Unifont from your system. Unifont is very useful for debugging, but not useful for reading.
Startup Speed
The default options favor correctness and completeness over speed, and can add many seconds to initial startup time in GUI mode.
However, when possible a font cache is kept between sessions. If you have persistent-soft.el installed, when you start Emacs the second time, the startup cost should be negligible.
The disk cache will be rebuilt during Emacs startup whenever a font is added
or removed, or any relevant configuration variables are changed. To increase
the speed of occasionally building the disk cache, you may use the
customization interface to remove fonts from unicode-fonts-block-font-mapping
which are not present on your system.
Unmapped Blocks
On the assumption that an extended Latin font such as Monaco, Consolas, or DejaVu Sans Mono is already being used for the default face, no separate mappings are provided for the following Unicode blocks:
Basic Latin
Latin Extended Additional
Latin Extended-A
Latin Extended-B
Latin-1 Supplement
Spacing Modifier Letters
though some of these remain configurable via customize.
Emoji
Color Emoji are enabled by default when using the Native Mac port on OS X. This can be disabled by customizing each relevant mapping, or by turning off all multicolor glyphs here:
M-x customize-variable RET unicode-fonts-skip-font-groups RET
Bugs
Calling set-fontset-font can easily crash Emacs. There is a
workaround, but it may not be sufficient on all platforms.
Tested on Cocoa Emacs, Native Mac Emacs, X11/XQuartz,
MS Windows XP.
Widths of alternate fonts do not behave as expected on MS Windows. For example, DejaVu Sans Mono box-drawing characters may use a different width than the default font.
Free International and Symbol Fonts
Free fonts recognized by this package may be downloaded from the following locations. For any language, it is increasingly likely that Noto Sans provides coverage:
From http://www.google.com/get/noto/
Noto Sans and friends ; 181 Unicode blocks and counting; sole
; source for these blocks:
;
; Bamum / Bamum Supplement / Kaithi
; Mandaic / Meetei Mayek Extensions
; Sundanese Supplement
;
; Also a good source for recently-added
; glyphs such as "Turkish Lira Sign".

Non-free Fonts
Many non-free fonts are referenced by the default settings. However, free alternatives are also given wherever possible, and patches are of course accepted to improve every case.
Chinese and Arabic Scripts
If you are using a language written in Chinese or Arabic script,
try customizing unicode-fonts-skip-font-groups to control which
script you see, and send a friendly bug report.
Unicode "Scripts"
Unicode also defines the notion of a "script" as a higher-level abstraction which is independent of "blocks". Modern fonts can report their script coverage, and Emacs may also access that information. However, this library ignores scripts in favor of blocks and glyphs.
Compatibility and Requirements
GNU Emacs version 23.3 and higher : yes
GNU Emacs version 22.3 and lower : no
Requires fonts-utils.el, ucs-utils.el
Uses if present: persistent-soft.el (Recommended)
React
Typescript
Django
Laravel
Facebook
Microsoft
Google
Alibaba
D3
Tencent
