Actually, I  believe the best practice way to achieve this is to use "$@"

"The difference between $@ and $*: Unquoted (don't do this!), none at
all: both equal $1 $2, with double quotes, "$@"
                expands each element as an argument: "$1" "$2" ...,
while "$*" expands to all elements merged into one argument:
"$1c$2c..."  (where c is the first character of IFS). You almost always
want "$@". The same goes for arrays: "${myarray[@]}"

That may solve the issue.
