I think perhaps the tests should actually try to generate a QR with this data too. As it will crash in AlphaNum::ord(). Would have revealed this bug earlier.

	public function testValidateString(string $string, bool $expected):void{
		$this::assertSame($expected, $this->dataMode::validateString($string));

		try {
			$qrCode      = new QRCode;
			$qrCode->addSegment(static::getDataModeInterface($string));
			$qrCode->renderMatrix($qrCode->getQRMatrix());
			self::assertTrue($expected);
		} catch(\Exception){
			self::assertFalse($expected);
		}
	}

This can also reveal the real bug while in main.
