Remove the regular space that you have first in the pattern:
str = str.replace(/[\u00A0\u1680โ\u180e\u2000-\u2009\u200aโ\u200bโ\u202f\u205fโ\u3000]/g,'');

try this:
var str = "Hello this is a test โof the site";
str= str.replace(/[\u00A0\u1680โ\u180e\u2000-\u2009\u200aโ\u200bโ\u202f\u205fโ\u3000]/g,'')
same as you did, but with out ' ' (regular space)

How to replace Unicode characters in the following scenario using javascript?
node.js - remove/replace Unicode characters javascript - Stack Overflow
Hey, so I should start by saying, I donโt know if the title is actually what Iโm trying to do... hence my problem.
Iโm getting data from a wordpress api and the titles have, what I believe are Unicode or ASCII codes for symbols in them, โ&โ and โ-โ for example are a string of numbers, within a string that makes up the title.
Iโm not familiar enough with the wordpress api to know how to get it without that if thatโs even possible and Iโve tried many different ways to just change these codes within the string into their symbols... please... someone put me out my misery and tell me how to do this?
I donโt seem to be able to google the correct thing, trust me, Iโve tried! I think itโs because Iโm not phrasing the question correctly, but I donโt know how to phrase it :S
Cheers for any help ๐๐ผ
Edit - Iโm using React Native. Would decodeURIComponent(); be an option? Iโm not looking to work with a uri but it seems to have the effect Iโm after from looking at some google results :S
Adapted from Semplice, following link from here.
[^\x00-\x80] matches any character not in the ASCII range.

function embolden( str, chr ){
return str.replace( /[^\x00-\x80]/g,
function (a) {
return chr == latin_map[a] ? '<b>' + a + '</b>' : a;
}
);
}
embolden( 'รกdรกm', 'a' ); // "<b>รก</b>d<b>รก</b>m"
I've tried this code, see if it's what you're looking for:
'รกdรกm'.replace(/./g,function(char){
switch(char.toLowerCase()){
case 'รก':
case 'ร ':
case 'รข':
case 'รฃ':
return '*';
break;
}
return char;
});
EDIT:
To replace all chars that don't belong to the ASCII table, just check if the char has a char code up to 127, since the ASCII table char codes are defined between 0 and 127 (notice that รก doesn't belong to the Unicode table, but to the Extended ASCII table, that comes from 0 up to 255):
'รกdรกm'.replace(/./g,function(char){
return char.charCodeAt(0)<=127 ? char : '<b>' + char + '</b>';
});
HTML entities get converted to actual unicode characters. Example:
document.body.innerHTML = "⇈";
console.log(document.body.innerHTML === "\u21c8"); // true
// Instead of a unicode esape sequence, you can write the
// actual unicode character. This is safe as long as you
// specify the correct encoding for your JavaScript files:
console.log(document.body.innerHTML === "โ"); // true
So when you read the innerHTML via $(this).html() or the textContent via $(this).text(), you need to look for the actual unicode character given by its unicode escape sequence "\u21c8" or directly "โ" and not its entity "⇈".
Try using String.fromCharCode()
The static String.fromCharCode() method returns a string created by using the specified sequence of Unicode values.
Syntax
String.fromCharCode(num1[, ...[, numN]]);
Examples
myString.replace(String.fromCharCode(8648),''); for โ
myString.replace(String.fromCharCode(8650),''); for โ
myString.indexOf(String.fromCharCode(84,69,83,84);
RegEx Improvements
The regex can be shortened by using case-insensitive match with i flag. We can remove the characters which are added as both lowercase and uppercase in the regex.
After removing lowercase characters regex will be as below
\?รร_|ล |ลฝ|ร|ร|ร|ร|ร|ร
|ร|ร|ร|ร|ร|ร|ร|ร|ร|ร|ร|ร|ร|ร|ร|ร|ร|ร|ร|ร|ร|ร|ร|ร|รฐ|รฟ|_ลโ|__|_
Here's live demo of regex
The regex can be further improved by using character class which will make the matches faster than OR conditions
\?รร_|_ลโ|[ล ลฝรรรรรร
รรรรรรรรรรรรรรรรรรรรรรรรรฐรฟ_]+
Adding + quantifier also has positive effect on the number of steps taken to match characters when the characters in the character class are consecutive/adjacent to each other.
Here's the demo on RegEx101, without + quantifierScreenshot and with + quantifierscreenshot applied on the same data. Note that in these demos, PHP is selected as the steps taken to match is not shown for JavaScript. Also, the regex is different, it also contains lowercase counterparts of those special characters as i flag is not working with PHP and don't want to apply u(Unicode) flag as it is not supported in JavaScript.
These demos are created only to show difference when + is applied on character class. The effect should be similar in JavaScript.
Note that the __(two underscores) are redundant as _ is already added in character class and with g flag it'll remove all occurrences.
Method Chaining
As replace returns a string, any other string method can be called on it. Multiple calls to replace can be chained.
str.replace(someRegexOrString, someString)
.replace(someOtherRegexOrString, someOtherString);
This is equivalent to
var temp = str.replace(someRegexOrString, someString);
var result = temp.replace(someOtherRegexOrString, someOtherString);
Replacing HTML
jQuery html() accepts a function which will receive the current innerHTML of the element on which the method is called as parameter and replaces the returned content to the element.
The code can be written as
$('.rte').html(function(index, currentHTML) {
return doSomeOperationOn(currentHTML);
});
Complete Code
With above changes, the code will be
$(document).ready(function() {
var regex = /\?รร_|_ลโ|[ล ลฝรรรรรร
รรรรรรรรรรรรรรรรรรรรรรรรรฐรฟ_]+/gi;
$('.rte').html(function(i, oldHTML) {
return oldHTML.replace(regex, ' ')
.replace(/[^\x00-\x7F]|\?/g, '');
});
});
$(document).ready(function() { is more readable than $(function() {. So, you may also consider using more expressive form.
The code may be correct in itself, but it does the wrong thing.
If by strange you mean unknown to someone who only knows English, that's no excuse for removing any letters you don't know. Would you really want to look at street signs for Cafs (which were legitimate Cafรฉs before)?
If you get strange character sequences like รยถ, that's an encoding problem and you need to fix it properly instead of hiding it.
If you really have to keep your code, at least be honest and replace each unknown character with a question mark or the Unicode replacement character so that it is clearly visible that something unexpected happened here.
