# isCharacterKey static method

bool isCharacterKey(

1. int keyCode

)

Returns true if the keyCode produces a (US keyboard) character. Note: This does not (yet) cover characters on non-US keyboards (Russian, Hebrew, etc.).

## Implementation

    static bool isCharacterKey(int keyCode) {
      if ((keyCode >= ZERO && keyCode <= NINE) ||
          (keyCode >= NUM_ZERO && keyCode <= NUM_MULTIPLY) ||
          (keyCode >= A && keyCode <= Z)) {
        return true;
      }

      // Safari sends zero key code for non-latin characters.
      if (Device.isWebKit && keyCode == 0) {
        return true;
      }

      return (keyCode == SPACE ||
          keyCode == QUESTION_MARK ||
          keyCode == NUM_PLUS ||
          keyCode == NUM_MINUS ||
          keyCode == NUM_PERIOD ||
          keyCode == NUM_DIVISION ||
          keyCode == SEMICOLON ||
          keyCode == FF_SEMICOLON ||
          keyCode == DASH ||
          keyCode == EQUALS ||
          keyCode == FF_EQUALS ||
          keyCode == COMMA ||
          keyCode == PERIOD ||
          keyCode == SLASH ||
          keyCode == APOSTROPHE ||
          keyCode == SINGLE_QUOTE ||
          keyCode == OPEN_SQUARE_BRACKET ||
          keyCode == BACKSLASH ||
          keyCode == CLOSE_SQUARE_BRACKET);
    }
