I have several pdf files I have created with pdfcreator from Word documents. In these initial pdf files the fonts are embedded. When I combine these pdfs in a single one, it looks like the fonts are not embedded properly: in the fonts list given by acrobat reader, the names of the fonts no longer appear (just things like 'T3Font_1') and there is no indication that they are embedded. I also notice some increase in the file size.
I would appreciate any help
