As you probably are aware unicode characters are multibyte characters.
GNU Parallel internally uses \257 for placeholder of replacement
strings.
Outside unicode \257 is rarely (if ever) used on the command line.
In theory it _is_ possible to make GNU Parallel deal correctly with
all characters, but so far no one has submitted a patch or been
willing to pay for the development.
The workaround (as GNU Parallel tells you) is to use a function:
myecho() {
echo 芦港 "$@"
}
export -f myecho
parallel myecho ::: foo
This also works if you have variables:
myvar="foo芦港 "
export myvar
myecho() {
echo "$myvar" "$@"
}
export -f myecho
parallel myecho ::: bar
/Ole
