Missing fonts in Acrobat 10

[Guest]

I am trying to help a user at my company.  He has Acrobat 10 and his coworkers have Acrobat 9.  He has a file he needs to edit and when he tried to copy text in PDF to Word or Notepad - text comes up as boxes - which I take as missing font.  I have same issue on my machine - only have Reader on mine.

I found the file has the following fonts which he does not have in his Fonts list - Innaru, Myriad, YDIYG340, YoonGothic

We looked on coworkers machine and don't see these on their machines

I have searched the net and don't see a lot of info about these fonts.

Is there some place he can find these fonts or should he remove Acrobat 10 and install Acrobat 9?

Ask the creator of the document for the missing fonts.

I found the creator's name in Properties - but that user is no longer with the company.  Any other possible solutions?
