[xml] Non-ASCII characters

[Dan Timis <timis rahul net>]

I am trying to save internal data from an application to xml, then 
later parse the xml to restore the internal data.  Some strings come 
from external sources and I noticed that sometimes there are characters 
above 0x7F.  In one instance, a string had two characters, first 'x' 
then 0xB2, which is "superscript two" in other words "x squared."

When I save to xml I get:

<string>x&#178</string>

When I use SAX to retrieve the string I get "x" then I get 0xC2 0xB2.  
I know very little about Unicode, but I found that "superscript two" is 
00B2 in the Unicode Latin-1 supplement.  What is C2B2?

I fixed the problem by skipping the 0xC2 and appending the the 
character that follows it to the string, but it feels like a bad hack.  
Is there a way to specify that I am working with 1-byte characters in 
the full range 00-FF?  Is there another way to solve this problem?

Thanks,
