a TOK 'b' lowercase in the style of Gentium Plus is the new version of the two reduced character set families, Gentium Basic and Gentium Book Basic. Those 'Basic' families only cover a limited range of Latin, and none of Gentium Plus's Ext Latin, Cyrillic, or Greek (both modern and ancient). Gentium Plus now extends the same 8 styles/weights of the previous Gentium Basic and to the full character set, packaged as two R B I BI families: Gentium Plus and Gentium Book Plus (also on github). This update brings many improvements, including better spacing and kerning, making it a better choice for modern and complex text.
