#9625 closed enhancement (invalid)

Support full range of allowed IDs in HTML5

Description

HTML5 seems to legalise all non-space characters for ID strings.

This creates a situation where you can have IDs which jQuery cannot match because its 'quickExpr' regular expression matches according to the more restrictive HTML4 standard.

See ​http://jsfiddle.net/2Zpn4/4/ for an example showing that document.getElementByID can return elements which JQuery cannot match.

Component: unfiled → selector
Priority: undecided → high

the /TR/ spec pages should not be used as reference as they are considered "trash" and exist only for record

The correct reference would be:

​http://www.whatwg.org/specs/web-apps/current-work/multipage/elements.html#the-id-attribute

As a note, attribute selectors _do_ work here:

Just need to escape the special chars.
