PDF Conversion and Unicode Error

[Maximiliano Sánchez]

Hello. I have the following error converting to PDF. I have no idea how to solve it and I can't find any other way to convert EPUB or MOBI files to PDF which is what led me to download Calibre. Thanks in advance for any help provided.

I'm using Calibre Portable, version 4.11.2 (2020 - 03 - 05) on Windows 7 Ultimate 64-bit.
Core i3 Processor. 16GB RAM. Lots of free disk space.

Converting from EPUB to PDF triggers the error, something about Unicode. Description below.
Converting from MOBI to PDF also triggers the same error.
Converting from EPUB to DOCX or TXT does not trigger the error. Conversion is successful.
Converting from MOBI to DOCX or TXT does not trigger the error. Conversion is successful.

Error seems to be connected with PDF Format and Unicode.
I have Adobe Acrobat Professional 9 installed on my computer but not running at the moment of the conversion. Could it have any influence on triggering this error?

Error:

Thanks a million good sir. You rock. Glad to be of help detecting an error.

Acrobat Pro does not support EPUB or MOBI. And apart from those low-quality websites which offer file conversion like ZamZar or pdfcandy, there seems to be no other way to do this conversion as of now. I've asked everywhere on forums and nobody seemed to know any method to convert from EPUB to PDF. I was about to convince myself that there was no possible way to convert EPUB and MOBI to PDF before discovering your program. I'm really lucky. Calibre will save the day.
