Deprecated SIL Corporate PUA characters

Gentium Basic and Gentium Book Basic supported characters

The supported character set for Gentium Basic and Gentium Book Basic is much smaller than for the main Gentium Plus font. The Basic fonts support only the Basic Latin and Latin-1 Supplement Unicode ranges, plus a selection of the more commonly used extended Latin characters, with miscellaneous diacritical marks, symbols and punctuation. In particular, these fonts do not support:

• Full extended Latin IPA
• Complete support for Central European languages
• Greek
• Cyrillic

A much more complete character set is supported in the Gentium Plus fonts. The Basic fonts were intended as a way to provide additional weights for basic font users before the complete Gentium Plus character set was finished. So please don’t request additional glyphs or characters to be supported in the Basic fonts—use Gentium Plus.
