Checks that a string contains only alphanumeric characters. A value passes when every character is either a letter or a digit, with nothing else in between. Use this to confirm that a code or identifier is clean before you act on it, for example to keep only product SKUs or reference codes that have no spaces, dashes, or punctuation. Letters from any language count as letters (including accented ones such as é or ü), and an empty value is treated as matching because it has no disallowed characters. Spaces are not allowed, so a value with a space in it does not match.
