JavaScript: How to use (backtick) ` in regular expression?

Question

In JavaScript, how do you use use the backtick (`) in a regular expression?

Sample code:

xtype: 'textfield',
regex: /^[a-zA-Z0-9àâçéèêîïôùû-.,:+*'()=&_ \s\u0060]+$/

Answer 1

backtick has no special meaning. you can use it as /`/, it will work fine.

Answer 2

Use unicode character searches and it should do it. Unicode character code for backtick is \u0060

So /\u0060/ should find you backticks. Tested it on RegexPal and it works.

However, as previous respondent correctly said, ` should just work fine without escaping. You must have the problem somewhere else if it doesn't. But using the unicode will ensure that it will definitely match.
