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 eici limit 10".replace("↵", "")

Works fine. But I want to know if there is any other way to remove these kind of unnecessary characters.

One more info that "↵" character is not available in code editors like sublime-text or notepad++. — ipankaj, Mar 17 '15 at 11:31
*way to remove these kind of unnecessary characters.* Do you wish to remove a set of characters like `↵`. If its just `↵` I would go for `replace` — nu11p01n73R, Mar 17 '15 at 11:32

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("")

While extracting from the html element use **String.replace(/[\n\r]/g, '')** will solve this problem. – ipankaj Mar 17 '15 at 11:42
The above comment's regex worked for me, other solutions didn't. – Frozen Crayon Dec 09 '16 at 13:08
@ArjunU. that means you're having actual line breaks in your string, not `↵` characters like the OP – Bergi Dec 09 '16 at 13:16
*String.replace(/[\n\r]/g, '')* Solved my problem. – Vikram Shetty Dec 13 '16 at 08:45
@ipankaj Can you please turn your comment into an answer? The others answers all seem inappropriate to handling this in JS. – Alex White Aug 22 '17 at 18:59

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

This is a safe option instead of using ↵ directly, it will be converted into unsupported character which may not in all environments. – Ashvin777 Mar 24 '20 at 13:17

You can also try regex as well,

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

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.

This answer points out too generic. OP is just asking how can he "replace" or remove a specific character, not how to use regex over a string. It can lead, as you clarify, to internationalization problems. – Sergio A. Jan 28 '20 at 12:27

I had the same issue but used the trim() function to clean out all extra spaces and ↵ characters.

str.trim();
