Need an editor which supports ANSI and UTF-8/UNICODE at a same Time

Hi there, is there any editor exists that will support both ANSI and UTF-8 at a same time?
Like

class A{
public static void main(String []a){
System.out.println("Hello");
System.out.println("हिंदी ");
}
}

If NOT, how can I find UTF/UNICODE code of a word? ie. UTF/Unicode of word "हिंदी "?
