How to determine a string is english or arabic?

Question

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

Answer 1

English characters tend to be in these 4 Unicode blocks:

• BASIC_LATIN
• LATIN_1_SUPPLEMENT
• LATIN_EXTENDED_A

• GENERAL_PUNCTUATION

  public static boolean isEnglish(String text) {
  
   boolean onlyEnglish = false;
  
   for (char character : text.toCharArray()) {
  
      if (Character.UnicodeBlock.of(character) == Character.UnicodeBlock.BASIC_LATIN
              || Character.UnicodeBlock.of(character) == Character.UnicodeBlock.LATIN_1_SUPPLEMENT
              || Character.UnicodeBlock.of(character) == Character.UnicodeBlock.LATIN_EXTENDED_A
              || Character.UnicodeBlock.of(character) == Character.UnicodeBlock.GENERAL_PUNCTUATION) {
  
          onlyEnglish = true;
      } else {
  
          onlyEnglish = false;
      }
   }
  
    return onlyEnglish;
  }
