How to use/transmit attr('id') containing special chars?

I have searched for some questions regarding this (like How to handle special characters in html element id/name in Jquery validation?), but unfortunately it doesn't help me, or I didn't undertsood the trick...

Let's say we have a button, with a class .bt and the id my|id. (or other special separators like ,:;|)

It doesn't seem to be possible to use it to match another element like $('#other_'+$('.bt').attr('id'))

You can see an example here.

So my question, is how to transmit those specials characters (,:;|) ?

Here's an example that still uses the id selector, but also allows for any special characters you want to be able to use:

$(document).ready(function () {
    $(".bt").on("click", function () {
        var escaped = $(this).attr("id").replace(/([,:;|])/g, "\\$1");
        console.log("escaped: " + escaped);
        $("#other_" + escaped).toggleClass("testing");
    });
});

This is a deviation from pure-jQuery solutions, but maybe in this case it's better to use native document.getElementById(...) function?

$(document.getElementById('other_' + $('.bt').attr('id')))

It reads a bit more verbose, but seems more clear/consistent/safe than mucking about with regexes.

Like this?

$('#other_' + $('.bt').attr('id').replace('|', '\\|'));

This worked:

$('[id="div_' + id + '"]').html(id);

instead of this: 

$('#div_'+id).html(id);

Fiddle here

-Edit-

New fiddle that shows usage of ,:;|
