Summary REGRESSION: charset="utf-8" (with quotes) doesn't work
Max Barel
Reported 2010-09-25 14:16:51 PDT
Beginning with r64889, any html code received from XHR is incorrectly interpreted against latin1, ignoring the "charset="utf-8"'directive in Content-Type. The last well behaving release is r64816 This bug have been there years ago and corrected. BTW. I'm pretty sure I already reported this bug (I mean with this very release information) but can't find it anymore.

Could you please provide an example page, or a reduced test case? Does this page work in Firefox? The only suspicious change in this range is one where we made charset name parsing more strict. If a resource used something weird like "utf_8" or "u-t-f-8", then we'd no longer treat it as utf-8. But common forms are all supposed to work.

Alexey, The test page was working in Firefox. Nevertheless, your comment directed me to the point. I was serving the header as: Content-type: text/html; charset="utf-8" rather than : Content-type: text/html; charset=utf-8 Notice that the encoding was a quoted string in the faulty page. The Content-type specification (http://www.w3.org/Protocols/rfc1341/4_Content-Type.html) allows quoted strings for parameter values, but I'm not sure the specific charset parameter does. Maybe not. So, it's up to you to decide if the parsing is indeed too strict. Should we allow quoted strings there? Beside, you may close the bug.

Thank you, this is certainly a bug. It's not even limited to XMLHttpRequest, in fact. Technically, the bug is in closed source networking code used by WebKit, but we'll need to add a workaround.

Created attachment 76270 [details] proposed fix Firefox also seems to support single quotes, but IE doesn't. RFC 2616 also seems to only allow double quotes.

This machine is having trouble with XCode. It's unclear why. I'll see if I can blow some caches or something.

I was obviously asleep at the wheel, and made a change to ResourceResponseCFNet.cpp instead of a Mac version. Thanks Alice for fixing it properly!
