croatian – Fonts for Croatian Glagolitic and other Croatian scripts
The package provides several fonts: Croatian Glagolitic (round—sometimes called Bulgarian Glagolitic, angular, Baška tablet, cursive, ligatures, the Baromić broken ligatures, calligraphic), Croatian Cyrillic, stećak ornaments and Croatian wattle patterns.
The fonts are provided as METAFONT source; some Plain TeX macro support is provided, including hyphenation patterns.
