This usually indicate a problem in the calling * application. * STRINGPREP_PROFILE_ERROR: The stringprep profile was inconsistent. * This usually indicate an internal error in the library. * STRINGPREP_FLAG_ERROR: The supplied flag conflicted with profile. * This usually indicate a problem in the calling application. * STRINGPREP_UNKNOWN_PROFILE: The supplied profile name was not * known to the library. * STRINGPREP_NFKC_FAILED: The Unicode NFKC operation failed.
