Quickstart

• Remove Unifont from your system.

• Install these fonts

  • http://www.quivira-font.com/files/Quivira.ttf ; or Quivira.otf

  • https://github.com/googlei18n/noto-fonts/raw/master/unhinted/NotoSansSymbols-Regular.ttf

• Use an extended Latin font for your default face, such as Monaco, Consolas, or DejaVu Sans Mono.

(require 'unicode-fonts)
(unicode-fonts-setup)

Testing

Keystrokes	Notes
C-h h	same as M-x view-hello-file
M-x list-charset-chars RET unicode-bmp RET	search for eg 210x
M-x list-charset-chars RET unicode-smp RET	if your display backend supports astral chars
M-x unicode-fonts-debug-insert-block RET Mathematical_Operators RET

Customization

M-x customize-group RET unicode-fonts RET

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

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:

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)
