Posted from: 85.227.154.145 by simonp@opera.com User agent: Opera/9.80 (Macintosh; Intel Mac OS X 10.7.3; U; en) Presto/2.10.229 Version/11.62 66905 1 ian 2012-04-20 18:37:34 +0000 Unless there's a compelling reason to do so, I can't see my considering this for very long... 66907 2 zcorpan 2012-04-20 19:30:05 +0000 It would make the prescan find charset declarations after <!-- --!> comments, which prevents scripts from running twice if the parser decides to change the encoding... $ grep -aEihzZB2 "<\!-[-]([^-]|-[^-]|-[-][^>])*-[-]\!>.+text/html[[:space:]]*;[[:space:]]*charset[[:space:]]*=" web200904 > bang-comment-then-encoding.txt Seems only two pages in this data set match, but they have an encoding decl before the comment as well. 70716 3 contributor 2012-07-18 17:21:44 +0000 This bug was cloned to create bug 18124 as part of operation convergence. 73977 4 ian 2012-09-16 03:42:10 +0000 Yeah, that's not very compelling. :-) The change to the spec would be relatively minor (just adding some more complexity to the "A sequence of bytes starting with: 0x3C 0x21 0x2D 0x2D (ASCII '<!--')" branch of the prescan algorithm), but it seems annoying to implement. I'm marking this WONTFIX. If you think I made the wrong call here, please reopen the bug. Especially if that's because you are implementing the algorithm and would rather support --!> than not support it.
