[Japanese language] Hiragana should match with Katakana in the search view

Note: Although I set the category "Mac", I believe that this applies to all the platforms (at least I encountered this on iOS, Android, macOS).

Japanese has 2 types of alphabets, Hiragana and Katakana. There is exactly one-to-one matching between each Hiragana and Katakana (e.g. あ = ア, い = イ. Think of them as like lower cases and upper cases of English alphabets, a = A, b = B). In the 1Password search view, Hiragana does not match with Katakana on any platform (Hiragana does match with Katakana in many search engines/features of other services).
Therefore, in order to search an item of which name is in Katakana, you need to type Hiragana and convert it to Katakana (this is usually how Katakana is typed with Japanese keyboards).
For example, when I tried to search an item "チケット...", which is Katakana, in 1Password, "ちけっと", which is equivalent to "チケット", does not match with the one I want.

So I needed to convert it to "チケット" to get the wanted item.

It's not really a good experience for me.
