RE: problem converting TTF using TTFReader

Thank you for your reply; unfortunately I got the same output when giving TTFReader the '-enc ansi' option.

I've been searching for ways to generate a Unicode cmap table and I've found tools to translate cmap tables but nothing to create one in an existing font. If anyone knows of an app that can do this, please let me know.

Yes. It is common for OCR and barcode fonts to omit the
cmap, for whatever reason.
Try the telliung TTFReader to use winansi encoding, assuming
the character range in the font fits the encodable range.

The tools that I use are FontLab (commercial):
http://www.fontlab.com/html/fontlab.html

and TTX (open source):
http://sourceforge.net/projects/fonttools/

You can do almost anything with TTX, but it requires some knowledge of the
font file formats. FontLab is going to be pricey if this is all you need it
for. Support for other encodings could be added to tools like FOP, but that
is likely to be even pricier. Best solution that I can think of is probably
to just purchase a different font (or hire someone to fix the existing one
-- but watch out for licensing issues).
