104016 - hexadecimial numeric character references (&#xHHH;) are not supported by browser

Status: VERIFIED WORKSFORME

(Core :: DOM: HTML Parser, defect)

Description

[Vlad Harchev]

hexadecimial numeric character references (&#xHHH;) are not  supported by browser (just ignored)!!! &#DDD; work fine of course. They need to be supported according to HTML spec.
I was shocked when I found that.

Reporter: Do you have a testcase for this?

Also, in future, please use the Bugzilla Helper for filing bugs:
http://www.mozilla.org/quality/help/bugzilla-helper.html
(among other things, it automagically adds your Build ID)

-> Normal

Hex, decimal, and named HTML entities work quite well in Mozilla. Here's a testcase:

Worksforme in Build 2001100903, but this has been working for a long time.
Reporter, what build were you using?

Sorry, I somewhat wrong. I use 0.9.2, the following html fragment:
<input value="a&#x31;">
DOES NOT SHOW "1" (0x31 is hex code of digit 1) in input field - only 'a'.
MS IE, lynx, links show "1" at the end of the input (i.e. input has string "a1" in it).

Marking WFM 2001100803 on Win2k.

Vlad: That build is abominably old. 

Please try a more recent build and reopen this bug if it still occurs for you:
http://ftp.mozilla.org/pub/mozilla/nightly/latest/
(as always, be sure to delete your old Mozilla directory before installing the
new one)

this appears to work
data:text/html,�

i think my current generator is
--
javascript:var a=''; var b="<a href='data:text/html,"; var c="'>test</a>"; for
(i=0;i<256;i++) a+="&#x"+i.toString(16)+";";
document.write(b+a+c);document.write(b+a.replace(/&/g,'&amp;')+c)--
I can try the same sort of thing for larger numbers, but getting this to work is
a wee bit of a pain...
Ok, replacing 256 w/ (2<<16) is a *bad* idea. eventually mozilla spent ~300mb of
ram and probably an hour thinking about it (Windows spent a lot of the interval
starving my irc client while trying to satisfy mozilla's memory needs).

If you're going to file a bug like this, please provide a testcase.

(collision...) verifying wfm, data:text/html,<input value="a&#x31;"> works
