No, "sort" and "join" use the same collating sequence by default.
It sounds like you have a different problem: you
weren't sorting by the same field that you were
joining on. For example, if you want to use plain
"join" then you need to sort via "sort -k 1b,1".
Or, if you want to use "join -t '|'" then you
also need to use "sort -k 1,1 -t '|'".
This is documented in the coreutils manual.
It may be that "LC_ALL=C sort" worked around your
problem on your particular test case, but it won't
work in general.
