Thanks all for the information. Summary is:
- 8.0 wasn't very strict, and allowed the illegal values in, instead
of mapping them over into UTF-8 space
- the values can be stripped with iconv -c
- 8.2 should be more strict
I'm in the midst of my upgrade to 8.2 now, hopefully the LATIN1->UTF8
conversion will now map the odd characters cleanly into UTF space.
