I don't think it's a UTF-8 problem. It's just that most people don't have "Å" on their keyboard.

> most people don't have

Many people don't know.

  cat /usr/share/X11/locale/en_US.UTF-8/Compose | grep Å

  <dead_abovering> <A>       : "Å"   Aring # LATIN CAPITAL LETTER A WITH RING ABOVE
  <Multi_key> <o> <A>        : "Å"   Aring # LATIN CAPITAL LETTER A WITH RING ABOVE
  <Multi_key> <asterisk> <A> : "Å"   Aring # LATIN CAPITAL LETTER A WITH RING ABOVE
  <Multi_key> <A> <asterisk> : "Å"   Aring # LATIN CAPITAL LETTER A WITH RING ABOVE
  <Multi_key> <A> <A>        : "Å"   Aring # LATIN CAPITAL LETTER A WITH RING ABOVE

Å - long press "a" on the ios keyboard and you get a whole list, slide your finger to the one you want, and let go.

Most people don’t have “é” on their keyboard, yet they still spell “fiancée”.

They only do if autocorrect allows it

Do they? Other than like the new yorker?

On mac this is just Opt + A
