Using special symbols in HTML and Javascript
Question
I'm trying to figure out what is the proper way to use the "not" operator (Negation) which looks like: ¬ (UTF-8: U+00AC ) in JavaScript. I could use:
<span>¬A</span>
But I'm not sure if it is the proper way and if its been supported on all (or most) of the modern browsers and mobile. I tried to find a previous topic on this matter but could not find any. The wanted result is to display this operator beside A .

Correct escape sequences for HTML are: ¬, followed by ';A', and for javascript - either '\\xACA' or '\¬A'.
"meta charset" is always advisable to include, but it does not affect the escapes.
I added ';' after the HTML escape sequence: for some reason it wasn't needed if instead of 'A' there is, for example, 'k', I didn't know. Semicolon has to be added.

That would be ¬ The "x" is needed because that's a hex encoding.
So
<span>¬A</span>
Make sure you include <meta charset="utf-8"> in your <head> .

If you are properly using UTF-8 (which is to say that your HTML, JS, and CSS files are all encoded in UTF-8, <meta charset="utf-8"> is present in the <head> , and HTTP headers all define the charset as UTF-8), there should be no need to encode the symbol at all. Simply write ¬ , exactly as you have done here.
The only symbols you need to encode are < and & (also ' and/or " in attributes). Most would also recommend encoding > and the non-breaking space, to avoid confusion. I encode all of these, but nothing else.
