Hello, 

How do I properly convert ruby string into backslash-escaped string? The
source is base64-encoded value and result should be escaped, so some
charaters must be encoded as '\xnn'. 

Example: 
Input is 'tracking@c3BlYw==.service' and expected result 
is 'tracking@c3BlYw\x3d\x3d.service'.

I've already invented the wheel by hacking some conversion routine to do
this and tried eval (not in production code, the problem mainly exists
in specs).
