Unicode converter for Gramcord fonts?

Years ago, the first substantive Biblical Studies software I purchased was Gramcord. The software was a hugely helpful tool at the time but has long since been surpassed by others.

Since the Unicode revolution has taken hold in Biblical Studies software, there are several tools that have popped up for converting legacy fonts (those that make English characters look like Hebrew or Greek). But, I’ve yet to find one that will work with the fonts that came with Gramcord—Greekpar.ttf and Hebpar__.ttf.

Has anyone found a tool that will convert text in these Gramcord fonts to Unicode-compliant characters?
