Maybe you should use something like

:echo system('echo '.shellescape(@").' | YourCommand')

Starting from some vim-7.4 version it is better to use

:echo system('YourCommand', getreg('"', 1, 1))

. This is basically the only way to keep NUL bytes untouched should they be present in the file. Passing @" in one or the other way will transform NUL bytes into NL (newline).
