I'm looking for a transliteration font to type sections of the taittiriya samhita with accents so it needs to have svarita accent (vertical line above ), double svarita (two vertical lines above) and anudatta (horizontal line underneath).  

Underline for the anudatta accent doesn't work too well because it obscures diacriticals underneath the letter.

I'm aware of the URW ITU font from Omkarananda ashram that comes with ITranslator 2003.  www.omkrananda-asrham.org .  But do any of the list members know of any other fonts I could use.

Thanks,

Harry Spier
