This typeface is a very lightly modified derivative of IBM Plex Mono.
The only modifications made were to disable the
ccmp tables, since
they were refusing to export properly, and to add the Powerline
glyphs for use in terminal applications.
If you only want the font files, just download PerplexedFamily.zip.
If anybody more skilled than I would like to figure out how to re-enable
ccmp tables (and explain it to me maybe?) I would be most grateful.
I'd like to have the font as close to the IBM original as possible,
with the addition of the Powerline characters.
