IUserCodeNormalizer Interface​

Canonicalizes a user-entered user code before it is matched against a stored code in the Device Authorization Grant (RFC 8628). RFC 8628 Section 6.1 recommends that the server strip readability punctuation the user may have copied (dashes, spaces), case-fold input for single-case character sets, and drop any characters outside the configured alphabet, so that equivalent user input is not rejected as invalid.
