I just wonder why in jquery we need to escape such an "unusuall"

trying to compare, but i just wonder about that).
The colon has special meaning in CSS, it denotes all kind of pseudo
selectors:

Even in standard CSS, if you want to select ids with a colon in it, you
need to escape it:
#foo\:bar selects <div id="foo:bar">

In prototype it may work with a colon in it if you use $() (which is
document.getElementById under the hood), but I doubt it would work with
Prototypes $$() (not tested though).
