Is there a kanji form of ああ, like there is for [斯]{こ}う, [然]{そ}う, and [如何]{どう}? I've searched online, but neither Jisho.org, Wiktionary, or Weblio list a kanji version for demonstrative ああ, like they do for [斯]{こ}う, [然]{そ}う, and [如何]{どう}.
I would assume [彼]{あ}あ, but the う/あ series of demonstratives break the [此]{こ}[其]{そ}[彼]{あ}[何]{ど} pattern and use different kanji from the rest of the demonstratives, so that's probably wrong.
I know there is [嗚呼]{ああ} and [噫]{ああ}, but those are use to describe the sound "aa" than the demonstrative.
Is there a kanji form of ああ? Or is it safe to assume that ああ has no kanji form?
