Nobody needs to hear this, but…

The "star" key on a telephone is actually represented by a sextile ⚹ according to ITU recommendation E.161

Many smartphone dialers get this wrong and use an asterisk *, full-width asterisk ＊, or asterisk operator ∗

@LilahTovMoon next thing we know we're gonna find out that the number sign, hashtag, and octothorpe are somehow distinct unicode characters that are imperceptibly different

@dan

I don't know about that, but hash and the musical sharp sign are quite different:

"# ♯"
