How to determine a string is english or arabic?

Question

Is there a way to determine a string is English or Arabic?

Answer 1

A minor change to cover all arabic characters and symbols range

private boolean isArabic(String text){
        String textWithoutSpace = text.trim().replaceAll(" ",""); //to ignore whitepace
        for (int i = 0; i < textWithoutSpace.length();) {
            int c = textWithoutSpace.codePointAt(i);
          //range of arabic chars/symbols is from 0x0600 to 0x06ff
            //the arabic letter 'لا' is special case having the range from 0xFE70 to 0xFEFF
            if (c >= 0x0600 && c <=0x06FF || (c >= 0xFE70 && c<=0xFEFF)) 
                i += Character.charCount(c);   
            else                
                return false;

        } 
        return true;
      }

Answer 2

You can usually tell by the code points within the string itself. Arabic occupies certain blocks in the Unicode code space.

It's a fairly safe bet that, if a substantial proportion of the characters exist in those blocks (such as بلدي الحوامات مليء الثعابينة), it's Arabic text.
