gnu-parallel encrypting files with spaces or special characters?

Question

I'm trying to encrypt a bunch of files with the code below:

find . -name "*.vi" | sort | parallel --gnu -j 4 --workdir "$PWD" '
    echo "Encrypting {/.} ..."
    gpg -r [e-mail] -o "/tank/test/{/.}.gpg" -e "{}"
';

This works fine, but only if the filenames have no spaces nor special characters (! or ') in them. Other than re-naming all the files, is there a way to make this code work?

It looks like too much quoting. Remember that GNU Parallel assumes {} is being parsed directly by the shell. Try removing "" around {} and {/.}:

# Avoid typing --gnu ever again
echo '--gnu' >> ~/.parallel/config

find . -name "*.vi" | sort |
  parallel echo Encrypting {/.} ...";" gpg -r [e-mail] -o /tank/test/{/.}.gpg -e {}
