Vesper contains a vast character set that is capable of typesetting over 88 Latin-based languages. There are four complete alphabets in each weight (upper case, lower case, small caps, & petite caps) and all contain full linguistic support for the supported languages.
There are 9 sets of numerals, plus pre-composed fractions and some smart OT code to help generate additional fractions. Currency symbols come in heights for lining and old-style/small caps in both proportional and tabular spacings.
Floating accents for all the cases are included, plus combining versions. Most of the punctuation also contains alternate versions to match each letter case. Some arrows and extra symbols round out the collection.
