Periods and colons in jQuery id selectors

[maros]

Dots and colons in jQuery selectors don't seem to work, although they are allowed by the W3C specification.

does not work $('#element.1224') <span id="element.1224"></span>

works $('#element_1224') <span id="element_1224"></span>

Special characters must be escaped with \\.
