Contains uppercase & lowercase letters, figures, accented characters and punctuation. These fonts also contain currency symbols ($, ¢, €, £, ¥), standard ligatures (fi, fl), common diagonal fractions (one-quarter, one-half, three-quarters), common math symbols, superscript numerals (1, 2, 3) and other symbols (including daggers, trademark, registered trademark, copyright, paragraph, litre, circled P, and "estimated" symbol, etc.).
Latin 2 (latin2)
Support for the following Central, Eastern and Baltic European languages [as well as Western]: Croatian, Czech, Estonian, Hungarian, Latvian, Lithuanian, Polish, Romanian, Serbian (Latin), Slovak, Slovenian and Turkish. In addition to 1252 Latin 1, these fonts support 1250 Latin 2, 1254 Turkish, and 1257 Windows Baltic.
Oldstyle Numerals (onum)
A.K.A., non-lining numerals, or lower case numerals
Discretionary Ligatures (dlig)
Rare ligatures such as st or ct, and unlike the
liga feature, they are not on by default, meaning that the user would specifically have to select the feature. By contrast, the liga feature will substitute the ffi ligature, for example, whenever the letters f, f and i are typed in sequence.
Swashes (swsh)
Primarily swash capital letters.
Ending Forms (end)
Not a proper OpenType feature. Often used in conjunction with swashes and alternates, it includes a handful of letters with tails that are only appropriate when used at the end of a word.
