No.

Not yet as there hasn't been sufficient need for it.

Currently, both `join` and `sort` take the -t option to specify
a field separator _character_. There was a related change
in `join` since v8.4-17-gf86bb69 where -t '' is used
to match on the whole line (which aligns with the
default operation of sort).

When implementing multi-byte character support for join
(not yet merged) I ensured that multiple bytes where allowed
only when they corresponded to a single character so
that in future we might support higher level functions like
'[:class:]'
