Create Cheat Sheets

Some Unicode fonts cover thousands of Unicode code points.

For your reference pdfcpu is able to produce cheat sheets.

A cheat sheet is a single-page PDF file containing a grid mapping the Unicode code points of a Unicode plane to font glyphs.

Most TrueType fonts cover (a subset of) a couple of code pages (256 code points each) of the Basic Multilingual Plane eg:

Some fonts - typically CJKV/Asian fonts cover a wide range of Unicode code points. 40000 glyphs in a single font sometimes covering more than one Unicode plane is not something out of the ordinary:

The following command will produce one cheat sheet for each Unicode plane with code points covered in a font in the current dir:

$ pdfcpu font cheat Unifont-JPMedium
creating cheatsheets for: Unifont-JPMedium

ls Unifont-JP*
-rw-r--r--@ 1 horstrutter  staff   3.8M Nov  5 01:32 Unifont-JPMedium_BMP.pdf
-rw-r--r--  1 horstrutter  staff   3.7M Nov  5 01:32 Unifont-JPMedium_SIP.pdf
-rw-r--r--  1 horstrutter  staff   3.6M Nov  5 01:32 Unifont-JPMedium_SMP.pdf

The following command will produce cheat sheets for all user fonts installed:
