Detect Other Languages in JavaScript

I recently needed to detect other languages in JavaScript, specifically I also needed to detect each character, from a different alphabet. There were quite a few hurdles to jump through but I figured it out and I’m happy to share.
I used their Unicode values. This may not be the best way, let me know if there is a better way!

Detecting a single character from another alphabet

For example if you need to find the Hebrew character א you would find it by it’s Unicode \u05d0.

if(value == "\u05d0")
{
//stuff happens
}

Detecting the entire alphabet

If you need to find if any Hebrew was used at all, it would look more like this.

var findhebrew = str.search(/[\u0590-\u05FF]/);
if(findhebrew >= 0)
{
//there is Hebrew in this string
}

Only allowing the other alphabet

If you need to only allow Hebrew characters in a string, stripping out the non-Hebrew characters would look like this would look like this.

mystring = mystring.replace(/[^\u0590-\u05FF]/ig,'');	

The point is, there is a block of Unicode for each alphabet, which allows you to test for a specific character, or the entire range if you need to.

That’s all folks!
