These fonts were created to support the testing of the font features in CSS, and are required to run some of the tests for those features. The fonts are modified versions of Gentium Basic, licensed by SIL under the Open Font License which allows modifications as long as the terms of the license are met. The original fonts were used to create the family 'CSSTest Basic'. This family has four faces and can be used for testing bold / italics. A subsetted version of this font with only glyphs for basic ASCII characters is 'CSSTest ASCII'. This was used to make the other variations. Most of the modications are to the name table and character maps, for the most part glyphs were not modified. The fonts are available for download both individually and as a ZIP package below. The files test.html and test.xhtml test that the fonts have been correctly installed.
