Hera is a monospace font which is a customised version of Source Code Pro which was originally created by Paul Hunt.
Hera consists mainly of glyphs from Adobe Source Code Pro mixed with glyphs from popular monospace fonts like Fira Mono, Inconsolata, IBM Plex Mono, etc.
Hera emphasises readability and uniformity for sigils and symbols which makes it suitable for use in coding environments.
