Why do I see incorrect fonts when I create PDFs from Word

When I first started using Acrobat (versions 3 through 5), it was an incredible product because it could create an exact copy of a document I created with a DTP program. I could send that PDF to someone who did not have the DTP program, yet the recipient saw exactly what I created in the DTP program. That's what made Acrobat great. It worked flawlessly.

Now I have Acrobat Pro XI, and I can't create a PDF from Word and get the correct fonts. I've seen quite a few messages on this forum and elsewhere indicating that other people have this problem, too. But I haven't found a solution. I've tried many things that are suggested--embed fonts, don't embed fonts, and different settings. Nothing seems to work. I've spent hours on this insted of doing the job I am paid for (writing). So I'd be very glad if anyone knows how to fix this.

A few specifics:

- Using Word 2010 and Acrobat XI Pro 11.0.3. Windows 64 bit.

- Most fonts are OK, but some appear to be substitutes. For example, some headings that are supposed to be Tahoma bold-italic come out as something different. It's a lighter weight font. I don't know what it is.

- Creation method from Word: Acrobat Tab, Create PDF or File > Save As PDF. Either way I get the wrong fonts.

- Print to Adobe PDF printer DOES produce the correct fonts, but this doesn't help because you don't get bookmarks (which are a critical part of our final PDF product).

- At one point it seemed that a Word setting, File > Options > Save > Preseve fidelty when sharing this document, but it didn't always work.

- I've seen this same problem on four computers, all using Word 2010 and Acrobat Pro XI.

Some messages suggest that rolling back to Acrobat 8 will solve this problem. It's hard to believe that's the only solution.
