Hi,
You need a wide range of unicode characters? First look: NRSI: Computers & Writing Systems:

The DejaVu-familie covers a wide range of unicode characters:

Old Standard is a multilingual font family suitable for biblical, classical and medieval studies as well as for general-purpose typesetting in languages which use Greek or Cyrillic script.

Just look for a wide unicode range ... Latin 1 Supplement contains ð, à(eth), þ, Þ (thorn), Umlauts and the german sharp s. The letter à ¿ (long s) is in Latin Extended A.
Bye bye
As a genealogist, I often transcribe documents with archaic letters like the thorn in old English. I don't mind if it's serif or sans, but I want a font like Times-Roman or Arial, not black letter or other fancy fonts.
Any suggestions?
