Jacques Distler ebc409e1a0 Ensure the_content REALLY is utf-8 
Our check that the the_content was valid utf-8 was rather busted.
This one works right. In particular, we needed to expand NCRs before checking.

Jacques Distler c8196cbe41 More Unicode Fun 
From Philip Taylor (via Henri Sivonen): disallow U+fffe and U+ffff.

Jacques Distler de125367b0 Update RDOC documentation. 
Update the documentation for sanitize.rb, to match current behaviour.

Jacques Distler 1911d18f65 Performance 
OK. This is a better way: define a custom TreeWalker which converts named entities to utf-8 as it goes. This avoids having to do an extra tree traversal in sanitize_rexml, AND avoids the trainwreck that is html5/inputstream.rb.

Jacques Distler 198d7847bd Performance 
My REXML::Element.to_ncr (and REXML::Element.to_utf8) is horribly slow. For long documents, it proves more efficient to serialize to a string, apply String.to_ncr (or String.to_utf8) and then Sanitize the string.

Jacques Distler 6fd6be8fea Sanitizer Fix

Fixed now.

Jacques Distler 4dd70af5ae HTML5lib is Back. 
Synced with latest version of HTML5lib, which fixes problem with Astral plane characters.
I should really do some tests, but the HTML5lib Sanitizer seems to be 2-5 times slower than the old sanitizer.
 2007-05-30 10:45:52 -05:00
Jacques Distler e1a6827f1f Rollback Switch to HTML5lib 
Apparently, HTML5lib does not handle astral plane unicode characters correctly.
Which makes it useless.
Return to the previous sanitizer.
 2007-05-29 23:57:39 -05:00

Unit tests, galore.
