use what software? thanks

what information/data do you want to edit?

but my fontographer can't do this

fontgrapher is an older program that hasnt been updated in a long time... that's why it can read some of the newer formats.

hmmm... i dont know if i know of any software that deals with those extensions... i will let you know if i come across of it.

The OpenType font format is an extension of the TrueType font format, allowing support for PostScript font data. OpenType was developed jointly by Microsoft and Adobe to produce a hybrid between Type 1 and TrueType fonts, with additional features that works on Macintosh and Windows computers. As part of the deal, Type 1 should receive built-in support in future versions of Windows.

I think the "Font Creator program" might be able to handle this. Go google and download the trial. Good program. Trial works for one month only.

Success and ... be nice to the cats.

Font creator doesn't support TTC format.
maybe only those guys who worked in Adobe or Microsoft hve such tools .

Maybe you can find some help here. PfaEdit seems to import OTF. http://pfaedit.sourceforge.net/

And, ehh, .... the cats.
