On: APFS is not safe to use with names which have Unicode normalisation issues

[tehabe]

Personally I think the current Normalisation Form D is awful, storing an ü as two characters is really annoying and even bash can't really deal with it in the version Apple uses. I really hope APFS will fix this. But we'll see.

[cryptonector → tehabe]

It's awful in great part because common input modes produce something close to NFC.

[kps → cryptonector]

Apple could of course change their keyboard layouts to produce something close to NFD. (OS X has always allowed keys to produce multi-character results.)

[cryptonector → kps]

But everyone else's input modes would still produce something close to NFC. Interop with the rest of the world matters. OS X is not the only OS.

[cryptonector → tehabe]

It's not bash, BTW, but the OS X input mode. A real irony there.

I used to compile my own bash from homebrew or alike and with that (newer) version, it worked w/o a problem.
