I have installed the latest version, but it does not work good. I guess that you replaced values for (cid:) with ascii. I have tried that, but it didnt worked. This is the result that Im getting:

I guess that you translated numbers inside the (cid:) to chars with ascii. In that way, you will get chars, but not correct chars. I fixed the issue with adding number 29 to each number inside (cid:... )

There is an issue in decoding strings written with TT2 font. Everything that comes after /TT2 1 Tf is decoded improperly.

it looks like this Type-0 font is a mess.

The font is broken, the glyphs have incorrect codes.
