When you run the IdFix DirSync Error Remediation Tool in your on-premises Active Directory Domain Services (AD DS) environment, "character" is displayed in the ERROR column for one or more objects.
This problem occurs if the tool identifies a character in an attribute that's not valid and that can't be synced from the on-premises AD DS environment to Microsoft Azure Active Directory (Azure AD).
