The download is a ZIP file containing 2 families of OpenType files (regular, italic, bold, bold italic), usable on Windows, Linux and Mac OS. You can open the release archive and read the README inside for some installation instructions.
The main proportional width typeface is Cynthia Handwriting. It supports Latin, Greek (including polytonic Greek), Cyrillic, Japanese hiragana and Katakana, Korean, the Braille display block, full-width Latin characters, certain IPA characters, certain dingbats and a very limited number of Chinese characters.
Kana and the 11172 hangeul syllables are proportional. Digits are fixed width. Spaces and dashes behave as a typesetter would expect.
The metrics of this version allow for more space between letters, especially those having vertical stems on their left or right (e.g. 'yp' and 'HM'), in Latin, Greek and Cyrillic.
There is a fixed width typeface that you can use in code editors, Cynthia Handwriting Mono. It features the same distinctions between I, l, | and 1 as the main typeface, as well as very clear [], <>, (), {} in a sans-serif design, but its character set support is limited to Latin, some Greek, some Cyrillic and the Braille display block.
The source files, for FontForge, are in the archive as well to allow you to modify the typeface. If you use these source files, you will need Python and Make to regenerate the OpenType font files.
— This deviation uses the excellent Lines paper by Ginnyhaha-Stock, as well as the open-source program FontForge, by George Williams. Thanks!
