Nice idea to hide it in a variable.

I'd come up with

in_input_funnies=`echo "$in_input" \
    | $SED -e 's![^}#$%&^_{~]!!g; s!\(.\)!\1'\\\\'
''!g' \
    | uniq`

which is fairly similar to the two examples above you gave, except
it's less clear. (Four backslashes because backslash escaped once for
the shell, and once for the ``-expression.)
