Re: [Devel] Errors in pstables.h

[David Turner]

Hello Artur,

  this bug seems strange. I can't answer right now about it, because
  I'm collecting the sources of all tables used in "glnames.py" in
  order to compare them..

  Is it me or the Adobe standard strings table (from the CFF spec)
  doesn't include "Cacute", "cacute" and "lslash" ??

Regards,

- David
