I know you can escape special characters with "\"'s, but I'm interesting in creating commands that will go to the terminal that include special characters, and these cannot read the backslashes well. 

As a simplified example, I'd like to have a command that looks like:

```
echo hello "w" or'l'd

```

Which could be achieved by something like

```
system(command="""echo hello "w" or'l'd""")

```

But R doesn't handle triple quotes. Is there another way? Even catching the output from cat() would be ok. e.g. newCommand = cat("echo hello \"w\" orld")

Thanks.
