Unamused. If anything, ambiguous characters should have been excluded. It's a very small reduction of keyspace in exchange for not entering the wrong passwords because of glyph similarities. Either you're expected to remember these 20-character monstrosities (which is going to be beyond the abilities of most people with 5+ accounts), or more likely you're going to be reading them from a password manager. Being ISO-compliant is all well and good, but it's been shown many, many times that making password restrictions this extreme causes more problems than it solves.
