RE: [flexcoders] Flex corrupting certain UTF-8 characters

Hard to say how any console output handles some of these chars.  Getting the 
string and the charCodes in them is probably best way to verify.  I don't think 
HTML entities work in UTF-8.  Make sure you're using valid encoding syntax.

Subject: [flexcoders] Flex corrupting certain UTF-8 characters





I am using an HTTPService to send XML to a java server. Most of what I send to 
the server arrives as expected, but certain characters are corrupted somewhere 
along the way, such as degree sign and the Euro currency symbol.  What we are 
seeing is that those sort of symbols have an  (A + circumflex) inserted before 
them.  When I create the XML on the client side, these corrupted characters do 
not appear anywhere in the debugging process -- at least, not in the Debug 
window or printed to the Console.  However, I do see the corrupted characters 
if I look at the XML that is created using Flash Tracer.

In addition to trying to send the character itself, I have also tried sending 
decimal and hexadecimal HTML entities, but these are treated the same way -- 
they all have the  (A + circumflex) added before the character.

The following is a test case to demonstrate the problem.  My project uses Flex 
SDK 3.3.  Has anyone seen this problem before?
