Thanks: if you can send us back some fancy examples for our collections
then that'd be great! (Like, with more than one C6.)

That is bad, indeed.
It seems that the xypic.map of 3.8.1 was not correctly updated to match
the updated .pfb fonts.
I would be grateful if you can try the following:
1. Get the file http://krisrose.net/xypic.map .
2. REPLACE your current xypic.map file with the new one.
3. REDO all your steps from the beginning.
4. TELL me whether it works!
If so then this will become version 3.8.2...

We did improve some things too, I hope...

I hope the updated xypic.map file fixes the problem - do tell! We can't
have 3.8 break too many 3.7 documents.
