As to my original question, here is the clear, simple answer.

It shows you how to go into the character map in windows (I have virtual machines for both Win 7 and XP. Both based on legitimate retail copies I own.). The map has a very useful help screen. Just select the character you want, copy into the buffer, and then insert the buffer into the document. I'm keeping a second .doc document with the characters I need (and commonly used words) and do a scrape and paste.
