Role of realpath in your workflow is not clear for me yet.

If you need to copy its result to clipboard then you may use xsel, 
xclip, etc.

realpath --zero "$file" |
     { IFS= read -r -d '' path ; printf '%q' "$path" ; } | xsel -bi

You may bind some key sequence to paste PRIMARY or CLIPBOARD content to 
BASH prompt quoted

_bind_x_yank() {
     local buffer head tail
     if [ -z "$READLINE_ARGUMENT" ]
     then
         buffer="$(xsel --output "${1:---primary}")"
     else
         buffer="$(xsel --output "${1:---primary}" |
             xargs --null printf '%q')"
     fi
     [ -n "$buffer" ] || return
     head="${READLINE_LINE:0:$READLINE_POINT}${buffer}"
     tail="${READLINE_LINE:$READLINE_POINT}"
     READLINE_LINE="${head}${tail}"
     READLINE_POINT="${#head}"
}
bind -x emacs -x '"\C-xY": _bind_x_yank'
bind -x emacs -x '"\C-xy": _bind_x_yank --clipboard'

[Esc] [1] [Ctrl+x] [y]
from clipboard or last [Y] from PRIMARY selection.

You even may define a desktop-wide shortcut that replaces selection 
content with its quoted variant. Neither task requires quoted output 
from realpath directly.

I am unsure what kind of debugger you use and what kind of escaping it 
needs.

P.S.
A corner case is a file path having trailing newlines
