I have a pdf where some texts are invisible or corrupted. If I open the pdf with Acrobat X it says "Cannot extract the embedded font". I am not the author so I can't request regeneration. Can I fix this? I tried using preflight or Illustrator but they didn't help.

If you don't need to edit anything, you could try PLACE the file into a new Illustrator document, select it, then Object > Flatten Transparency > High Resolution > (check "Convert All text to Outlines").

If that works, at least you have a vector graphic to play with. However, if that also fails, then you might be out of luck.

Do you feel comfortable sharing a file? This may be a job for something more robust like PitStop: I could take a look at it and advise.

Can you open the pdf on another computer without any issues? Acrobat X is pretty old, can you download the free Acrobat Reader and try that? https://get.adobe.com/reader/

How does the pdf look when you use a non-Adobe viewer, like a browser? if it looks OK, you could take a screen shot and save the image as a pdf from Acrobat (far from ideal, of course). Try placing it into InDesign and exporting to a new PDF, (admittedly a long shot). I assume you tried the preflights to embed missing font, fix potential problems, and fix font encoding.

The problematic embedded font was cmti10 from jsMath. Is there a way to replace embedded font with system font?

I'm not sure that would work. Check your page display preference to use local fonts. Did you try the preflight fixups? (Tools> Print production> Preflight> Fixups). Actually, the preflight options are different in Acrobat X. Can you attach a sample page of your PDF?
