Your POC works for me, the PHP iconv code converts the UTF-8 byte
sequence 0xef 0xbc 0x9C to ASCII '<'. Looks like PHP applications
may be at risk.
The java CharsetDecoder class does not. (I don't think this will be
JRE specific, but I tested the IBM JRE...).
The perl Encode module does not.
Anybody have an IIS server handy, to test out how .NET handles this?
