How to remove ↵ character from JS string

Question

I have a string like

↵my name is Pankaj↵

I want to remove the ↵ character from the string.

\"↵select * from e         


        

Answer 1

Instead of using the literal character, you can use the codepoint.

Instead of "↵" you can use "\u21b5".

To find the code, use '<character>'.charCodeAt(0).toString(16), and then use like \u<number>.

Now, you can use it like this:

string.split("\u21b5").join(''); //split+join

string.replace(/\u21b5/g,'');  //RegExp with unicode point

Answer 2

works fine.

If it works fine, then why bother? Your solution is totally acceptable.

but I want to know is there is any other way to remove these kind of unnecessary characters.

You could also use

"↵select * from eici limit 10".split("↵").join("") 

Answer 3

You can also try regex as well,

"↵select * from eici limit 10".replace(/↵/g, "")

Answer 4

With something like

s.replace(/[^a-zA-Z0-9_ ]/g, "")

you can for example keep only alphabetic (a-zA-Z), numeric (0-9) underscores and spaces.

Some characters require to be specified with a backslash in front of them (for example ], -, / and the backslash itself).

You are however going to run into problems when your start deploying to an international audience, where "strange characters" are indeed the norm.
