No Unicode Mapping Warning

[smyaseen]

Hi,

While reading a PDF, I'm getting the "No Unicode mapping..." warning. I want to ask if it's ok to ignore this, or there is a problem? What can I do to solve this? I can't share the PDF due to confidentiality.

I can't really help here. This is a message from the underlying PdfBox library, that I'm using to render the PDFs.
It basically tells you, that the used font does not have a proper mapping for some characters. Most likely a fallback font will be used, but please check with PdfBox: https://pdfbox.apache.org/

I understand. Thank you.

One thing, is it ok to ignore this warning?

[finsterwalder]

Like I said, I'm not an expert. And i don't know the impact.
Best case: Nothing to worry about.
Worst case: chars are not rendered and you don't see differences in those chars.

Alright thank you.
