+early 20th century, reviving a specific type of Modern (classicist) style of
+serif typefaces, very commonly used in various editions of the late 19th and
+early 20th century.
+
+The font supports typesetting of Old and Middle English, Old Icelandic,
+Cyrillic (with historical characters, extensions for Old Slavonic and
+localised forms), Gothic transliterations, critical editions of Classical
+Greek and Latin, and many more.")
