Apply the same methodology, as in Revision 432,
to the category chunk-handler. This completes
the replacement of all the code that looks like
if string.is_utf8?
do something
else
complain
end
with code that looks like
string.purify
do something
Start work (which may not pan out) on a new sanitizer. Right now, it passes
all but 1 of the HTML5lib Sanitizer's unit tests. But it doesn't do much
of anything to ensure well-formedness. This is not an issue for Maruku-processed
content, but it is a concern for <nowiki> blocks.
(One solution would be to use the HTML5lib parser on <nowiki> blocks.)
In any case, this baby is 3 times as fast as the HTML5lib sanitizer.
Fixed a bug in the HTML5lib tokenizer (affects S5 slideshows).
Some miscellaneous code cleanup. In particular, don't bother with zapping control characters;
instead, rely on is_utf8? method to raise an exception (which we do anyway).
