[2][3] It was one of the first typefaces to be part of Adobe's Originals programme, designed to feature a large range of styles for professional use.
Slimbach made some changes to the font when revisiting it for the OpenType release, and Adobe does not guarantee identical character metrics.
[4] This means documents developed using one font file should not be switched to using another, at risk of lines breaking in different places.
Adobe donated the Utopia typeface (in the form of PostScript Type 1 files) to the X Consortium, for use in the X Window System, a popular graphical environment for Unix workstations.
[8] On November 17, 2006, Karl Berry, the TeX Users Group President, gave irrevocable permissions of the font to any third party and it constitutes free software.
[9] Another further development of the original was made by Andrey V. Panov, in an OpenType derivative called Heuristica (also: "Эвристика"), with the primary intent of adding Cyrillic symbols.
Andrey has also incorporated Hàn Thế Thành's Vietnamese glyphs in Heuristica and the development of the project is open.
