   as far as i know there are no systems based on UTF-16 that disallow bare surrogates

   UTF-16 doesn’t exist, it’s always WTF-16

     @fanf Hmm.

     JavaScript allows unpaired surrogates.
     Java allows them, at least in some cases.
     Windows APIs allow them.
     USB probably doesn't care.

     Where else is "UTF-16" even used?

     UEFI?
     .Net?
     What about MySQL?

     @rallias @fanf Yeah, utf8 is an alias for utf8mb3 which doesn't represent codepoints over 65535.

     @ryanc @fanf iirc, MySQL recommends using utf8, but because of some historic bullshit there's a couple built in variants, of which utf8mb4 is the correct option if you want compliant utf8
