The Script_Extensions property values for some characters contain Hiragana, Katakana, or Bopomofo, when they should only contain Han. The Unicode Technical Committee is considering removing the Hiragana, Katakana, or Bopomofo in these cases, and would like feedback as to any that should not be changed, and any others that should be. Public Review Issue #316 contains details of a proposal to remove these items from Script_Extensions.
