UniCover is a simple command-line tool displaying information about Unicode coverage of system fonts. It should work on systems that utilize Fontconfig (Linux and other Unix-like).

Dependencies: Python-fontconfig, freetype-py.

Installation

In most cases issuing the following command will be sufficient:

pip3 install --user UniCover

If you get an error from Python Fontconfig library, try installing its header files first, eg. for Debian or Ubuntu:

sudo apt install libfontconfig1-dev

Usage

Basic usage

Display all characters contained given font family or font file

Returns list of characters grouped by Unicode blocks.

unicover -f 'Liberation Sans'
unicover -f /usr/share/fonts/TTF/LiberationSans-Bold.ttf

unicover -f 'Liberation Sans' -g    # lists only Unicode blocks
unicover -f 'Liberation Sans' -o    # omits summary line (total number of characters)

You can discover what fonts are installed in your system using Fontconfig:

fc-list : family        # lists font families
fc-list : file family   # lists font files with families they belong to

List all system fonts that contain the specified character

unicover -c ₹
unicover -c 54f6

unicover -c ₹ -g        # lists only font families
unicover -c ₹ -o        # omits summary line (total number of fonts)

System fonts summaries

Display all Unicode blocks supported by the system fonts

unicover -g

List all characters supported by the system fonts

unicover -l
unicover -gl            # group characters by Unicode block

Note: output will be very long.
