Nothing specific to GTK but in D and other programing languages the \ is 
used as an escape character, so you can use special characters in your 
sting like `\n` for a newline. But this means you will need to use \\ to 
get an literal back slash.

You can also use an wysiwyg string by using `r"` at the start so what 
you type is what you get.
