I didn't like the idea of hacking jQuery to make selectors with these
special chars work, but as it turned out, that is what should be
expected! From the CSS spec:
In CSS 2.1, a backslash (\) character indicates three types of
character escapes.
[...]
*Second, it cancels the meaning of special CSS characters.* Any
character (except a hexadecimal digit) can be escaped with a backslash
to remove its special meaning. For example, "\"" is a string consisting
of one double quote. Style sheet preprocessors must not remove these
backslashes from a style sheet since that would change the style sheet's
meaning.

Thus, I think a selector like "#my\:elem" is perfectly valid and that
should be part of jQuery's selector engine...
