Winni Neessen	a1efa1a1ca	Remove redundant empty string check in SCRAM normalization ... The existing check for an empty normalized string is unnecessary because the OpaqueString profile in precis already throws an error if an empty string is returned: https://cs.opensource.google/go/x/text/+/master:secure/precis/profiles.go;l=66	2024-11-08 22:44:10 +01:00
