The mission of the Scientific and Technical Information Exchange (STIX) font
creation project is the preparation of a comprehensive set of fonts that serve
the scientific and engineering community in the process from manuscript
creation through final publication, both in electronic and print formats.
This package includes fonts containing glyphs called out from the Unicode
Private Use Area (PUA) range. Glyphs in this range do not have an official
Unicode codepoint. They're generally accessible only through specialised
software. Text using them will break if they're ever accepted by the Unicode
Consortium and moved to an official codepoint.
