Hello Danny,
It turns out that the encoding for these files are `Hebrew -
Windows 1255` which we currently don't support unfortunately. That's why
PDFNet complains because in our old sdk, only UTF encoding is accepted
when converting text to pdf.
If you can try our latest
nightly builds with utf-encoded files, the problem should be resolved.
I have attached a utf-8 version of one of the attachments you sent in
this email. Feel free to give it a try using our latest nightly builds.
Please let me know if this works for you, and if you have any further questions.
Regards,
Renchen
