Question

I need to replace the unicode characters defined on here

I have got this so far but it seems to remove all space including standard spacebar ones:

va         


        

Answer 1

Remove the regular space that you have first in the pattern:

 str = str.replace(/[\u00A0\u1680​\u180e\u2000-\u2009\u200a​\u200b​\u202f\u205f​\u3000]/g,'');

Answer 2

I guess you should use the escape sequence for spaces (15.10.2.12 of the norm) which is \s, and that you want to replace multiple spaces by a single one :

str= str.replace(/\s+/g,' ') ;

Answer 3

I think you can simplify, try this:

str = str.replace(/(?! )\s/g,'');

Answer 4

try this:

var str = "Hello this is a test  of the site";
str= str.replace(/[\u00A0\u1680​\u180e\u2000-\u2009\u200a​\u200b​\u202f\u205f​\u3000]/g,'')

same as you did, but with out ' ' (regular space)
