Hi,
The attached file illustrates a UTF-8 decoding bug in the HTML parser,
which can be recreated with:
$ xmllint --html utf8bug.html
The last one or two characters in the document are corrupted, and
xmllint reports an encoding error. However, the text is in fact
correctly encoded, as can be demonstrated by pasting it into an XML
document, or just deleting some unrelated text from earlier in this
document, which fixes the problem.
As can be seen from the full example (utf8full.html) after the corrupted
character the parser appears to switch back to a single byte encoding,
so all subsequent multibyte UTF-8 text is also corrupted.
This appears to be caused by some kind of buffering bug, perhaps a
multibyte UTF-8 character is overlapping the end of a buffer, and the
buffer is not being expanded correctly?
Best regards,
Michael
