The issue is probably that the characters which are rendered using the subset font have a custom encoding - the numeric representation of the characters does not correspond to ASCII, Latin-1 or any other common encoding.
See
- PDF Font encoding
- Unsearchable, uncopiable PDF document
- How do I know if the fonts in a PDF file are embedded or not?
This means there isn't an easy workaround.

In this situation, I have printed the PDFs using the Adobe PDF printer via a high resolution (1200 dpi+), high quality image(up any settings you can). Then, I OCR the image PDF leaving me with a searchable and workable PDF.
When I have many PDFs to do over thousands of pages, I have opened multiple PDF windows at once to do this simultaneously using multiple cores for multiple PDFs. It is a PITA, but it works.
Hopefully your files are small! I've done this to upwards of 10,000 pages once (building code books). Not fun.

Thanks for the answer . But how come the pdf viewer is able to correctly interpret it ?

Probably because the encoding is embedded in the PDF, not the program.
