Converter string to raw

[modolo]

Hi!

I know it is possible to create raw strings with r or R like:

let msg = r"tHellon" # raw string

But if I have a string that was not created as raw, is it possible to make it 
raw?

let msg = "tHellon" # string

let raw_msg = MakeStringRaw(msg) # my wish

It is possible? I looked in the documentation and did not find anything 
relating.

Thanks,

Marcelo Módolo
