------- Comment #9 from webkit-bugs at gentlyusedunderwear.com  2008-03-18 19:00 PDT -------
Sadly, this is not a layering violation any more C10 of the Unicode 5.0
specification Chapter 3 (http://www.unicode.org/versions/Unicode5.0.0/ch03.pdf)
says:

"When a process interprets a code unit sequence which purports to be in a
Unicode character encoding form, it shall treat ill-formed code unit sequences
as an error condition and shall not interpret such sequences as characters. "

It may have been a layering violation when the XML part of this was originally
written. But it isn't as of Unicode 5.0, since it explicitly says "error
condition". And these XML specs are free to specify exactly what happens in an
"error condition".

(Many Text based apps just replace the invalids with U+FFFD
(http://www.fileformat.info/info/unicode/char/fffd/index.htm) as it is far
worse for these applications to bail when encountering invalid codepoints)
