Another problem is created by PDF fonts as they are usually embedded in the PDF le.
In DWG or DXF, the fonts have to be taken from the system. Since the fonts are embed-
ded in PDF, the characters are no longer coded, for example per the ASCII table. PDF
les often use Identity-H fonts with no rule regarding character encoding. As we are not
allowed to extract fonts from a PDF to a Windows system, Print2CAD looks for similar
fonts in the Windows system and denes these as substitute fonts for the DWG or DXF
le getting created..
