For those of you looking for an improved version with more/better accents etc: David Kerhoff has allowed me to rework some of his fonts and offer them with a (very generous) commercial license.
So if you need a professional quality Unicode OpenType or TrueType version of this font with a multilingual and expanded character set - you will find it here:
