These are pretty much guaranteed not to be related to the original 
problem. All of these reports are Mac VM issues and the original report 
was on Windows Vista. I'd like to raise a slightly different question 
though:

At Qwaq, we've changed our utf8ToSqueak version to assume that the input 
is in Latin-1 when "invalid input" is encountered. That's because we've 
never found a situation where one wouldn't be better off to silently 
accept the input (regardless of whether it's actually UTF-8, Latin-1 or 
whatever else) instead of blowing up. I wonder what people think about 
that? It's along the lines of "lenient on input, strict on output" which 
is generally a good rule.

If people think it's worth it; the change is rather trivial to make.

Cheers,
