update: the Turned A in Turn A Gundam
Few days ago, i discussed whether the symbol “upside-down A” in title of anime series 〈Turn A Gundam〉 should be the unicode ∀ (U+2200; FOR ALL) or Ɐ (U+2C6F; LATIN CAPITAL LETTER TURNED A). I got the answer. Thanks to Maiko Kinzel Engelke and Benjamin Howard Lee. See bottom at Unicode Semantics: the ∀ in Turn A Gundam.
