Guix

Tamzen is a fork of the Tamsyn font. It is programmatically forked from Tamsyn version 1.11, backporting glyphs from older versions while deleting deliberately empty glyphs (which are marked as unimplemented) to allow secondary/fallback fonts to provide real glyphs at those codepoints.

The TamzenForPowerline fonts provide additional Powerline symbols, which are programmatically injected with bitmap-font-patcher and later hand-tweaked with the gbdfed(1) editor:

1. all icons are expanded to occupy the maximum available space

2. the branch of the fork icon ( U+E0A0) was made larger than the trunk

3. for the newline icon ( U+E0A1), the N was made larger at the bottom

4. the keyhole in the padlock icon ( U+E0A2) was replaced with // lines.
