doc: prefer ö to $'\u7530'

* doc/coreutils.texi (Character arrays): Avoid using shell
notation like $'\u7530' since this isn’t in POSIX yet. Instead,
use ö and Ł which should work in all texinfo output formats.

 GNU @command{tr} fully supports only safe single-byte locales,

 Unfortunately, this means GNU @command{tr} will not handle commands

 POSIX does not clearly specify the behavior of @command{tr} in locales
 where characters are represented by byte sequences instead of by
 individual bytes, or where data might contain invalid bytes that are
