Its design goal is to "provide a single Unicode-based font family that would contain a comprehensive inventory of glyphs needed for almost any Roman- or Cyrillic-based writing system, whether used for phonetic or orthographic needs."[1]
Version 6.2 of the font, with over 3,800 glyphs,[4] current as of 2023[update], was released on 1 February 2023.[5]
Gentium Book Plus font with 'a' and 'g' set to primer styleAndika font with two features selected
Variant forms of many characters can be chosen in the word-processor. For example, for primer-style 'a' and 'g', append ss01=1 to the name of the font in the font-selection window.[6] (Features are appended with a colon and linked with an ampersand – see images at left.) Alternatively, customized versions of the fonts can be created with TypeTuner, prior to download, that have those forms preset.[7]
Features that may be chosen include small capitals, primer-style 'a' and 'g', roman-style 'a' and 'g' in italic typeface, variant forms of capital 'Ŋ', large modifier letter apostrophe and Saltillo, Vietnamese-style diacritics, Serbian-style italics (in Cyrillic), staveless tone letters, and automatic fractions.[6]
