public static bool IsValidateSubscriptionNameOrId(string subscription)

public static Uri ValidateAuthorityHost(Uri authorityHost)

public static string ValidateTenantId(string tenantId, string argumentName = null, bool allowNull = false)

As tenant id is used in constructing authority endpoints and in command line invocation we validate the character set of the tenant id matches allowed characters.
