Nice one CAB 
This was my version (I'll add it to my site when I get a chance!)
Lee... Thanks. That's exactly what I wanted a few days ago
Here's my story:
When there's a need to distribute standard drawings to a contractor, I usually export them to WMF and then I use MS WORD to create the pdf.
It suits my need. Unfortunately some portion of the pdf consist of paragraph text still can be disassembled from pdf.
With your code, problem solved. Texts are words, not one sentence.
