We normally add a match for “illegal” characters in situations lile 
these, for example:

	{	name = "string.quoted.double.hex.python";
		begin = 'x"';
		end = '"';
		patterns = (
			{	name = "invalid.illegal.not-a-hex-character.python";
				match = "[^\h\n]+";
			}
		);
	}

That way, if you have: `x"abcq123"` then `q` will be highlighted as 
illegal (most themes should give it a red background).
