At first, Everson Mono was a collection of 8-bit fonts containing glyphs for tables in ISO/IEC 10646; at that time, it was not easy to edit cmaps to have true Unicode indices, and there were very few applications which could do anything with a font so encoded in any case.

A single Unicode font file incorporating most or all of the characters from all of the previous separate Everson Mono files was named "Everson Mono Unicode" in 2003, but since 2008 the single large font has been named simply "Everson Mono".

Everson Mono version 7.0.0, dated 2014-12-04, contains 9,632 characters (9,659 glyphs).

In short, this font covers the following scripts: Armenian, Canadian Syllabics, Cherokee, Cyrillic, Georgian, Greek (excepting Coptic), Hebrew, Latin, Ogham, Runic, see below for details.

To use the font in any substantial way for personal or commercial purposes, Everson requires a €25.00 license fee, which covers up to three computers; anyone seeking to redistribute the font must seek express personal permission from Everson, and any use of the font on more than three computers also requires a custom license.
