I have a pdf that was sent to an editor for markup.

The returned pdf came back with missing fonts.

Using Enfocus Pitstop I was able to find these facts:

 

Both pdfs are Acrobat 1.7 with the fonts embedded and embedded subsets

The "ToXXXXX" pdf line on page 377 is an embedded T1
There is also NO word spacing applied to the sentence
 
The "FromXXXXX" pdf line on page 377 is Composite T1 while the letter "f" in the sentence Viewfinder is T1
There is significant word spacing and slight character spacing on the pdf returned from XXXXX.
"FromXXXXX" The sentence is broken from a sentence to letters and words
There is some font substitution happening. 
 
I did find this:
Composite fonts are either OCF (Original Composite Fonts) format, an earlier and rapidly dying method for handling East Asian font needs, or the Adobe composite font mechanism for creating "virtual fonts" where some glyphs in one font are replaced by ones from another font.
 
what would cause this ?
