Assuming that the fonts in question are actually embedded in your PDF file(s), Generally, the type of problem you are encountering is due to either fonts that are corrupted or invalid in some way prior to being embedded in the PDF file or possibly a valid font being improperly embedded in the PDF file, the issues often associated with either missing glyphs, improper or missing encoding tables, or improper font type specification. We have seen this quite often with third party PDF file creation libraries.
Please try to embed the fonts into the PDF as described below and see if that works:
After the PDF is generated, open it in Adobe Acrobat Pro, go to Tools > Preflight to embed fonts into the PDF. Save this new version of the PDF and distribute it to your end users rather than the original one.
