Special characters as function names in javascript

Question

I have:

function _(x){
 return document.getElementById(x);
}

I would like to do the same think for getElementByClassName, but aside from "$" are there any other special characters I can use? I was thinking about may å or some accented character, but I don't know if it will work or not.

Is there any downside to doing something like this?

function å(x){
  return document.getElementByClassName(x);
}

http://stackoverflow.com/q/1661197/613130 function names should be the same. — xanatos, Aug 03 '13 at 21:03
@xanatos can you post that as an answer so I can mark it correct? — Jacques ジャック, Aug 03 '13 at 21:06
Should be closed as duplicate IMO. *"Is there any downside to doing something like this?"* Is a bit subjective I think. Depending on what language you use on your computer, some names might be difficult to type. — Felix Kling, Aug 03 '13 at 21:07

In general the name of a function/variable must start with _, $ or a letter (even accented/with other diacritics)

Here they spoke at length of it: What characters are valid for JavaScript variable names?
