this began as a one-word change to the spec (manpage): that

${foo:1:2} operates on characters ipv bytes – which means:
‣ set +U: octets
‣ set -U: MirOS OPTU-8 characters

for consistency I also adapted ${#stringname} to deliver the
length in characters ipv bytes; more may follow; for example
I’d like a way to expose the string width.

you can already get the MirOS OPTU-16 of a character in the
WTF-8 (「set -U」) mode with something like
│ typeset -Uui16 -Z7 x=1#${stringname:position:1}
which will correctly use the PUA EF80‥EFFF mapping for octets.

due to this being an incompatible change, bump to R38

also change the unicode-hexdump sample regression test and
add two news for ${x:1:2} and ${#x} checks in A/W mode ☺
