Removing Vowels from Hebrew Unicode Text

Posted June 3, 2005 – 4:28 pm by Yakov Shafranovich in Programming

One of the questions that recently came up is how to remove vowels from Hebrew characters in Unicode (or any other similar language). A quick look at Hebrew Unicode chart shows that the vowels are all located between 0×0591 (1425) and 0×05C7 (1479). With this and Javascript’s charCodeAt function, it is trivial to strip them out:

function stripVowels(rawString)
{
	var newString = '';
	for(j=0; j<rawString.length; j++) {
		if(rawString.charCodeAt(j)<1425
			 || rawString.charCodeAt(j)>1479)
		{ newString = newString + rawString.charAt(j); }
	}
	return(newString);
}

You can test it below:
