[xml] strange encoding behavior when parsing HTML files

[Aaron Patterson <aaron patterson gmail com>]

Hi,

There seems to be strange behavior in libxml2 with regard to encoding
when parsing an HTML file.  If an HTML file contains a meta tag
hinting at the encoding, libxml2 will use the encoding in the meta tag
*unless* there are strange characters before the meta tag.

If there are strange characters before the meta tag, libxml2 will
guess the encoding and use the guessed encoding for the rest of the
document even though the meta tag reported the correct encoding.
What's worse is that libxml2 will report that it used the encoding
from the meta tag when outputting the content of the document
indicates that it did not.

Here is an example of the behavior in action:

fail.html fails, and success.html "does the right thing".

Should I report this in bugzilla?

Thanks!
