Subject Re: Escaping unicode reference in slashy string
Date Tue, 09 Feb 2016 01:40:00 GMT
Unicode processing is done before anything else. For your case, you
need to make it not look like a unicode sequence - which you rightly
did with the double backslash variant. But you then need to pick the
GString form that does the appropriate thing with the sequence of
characters that passed through the initial parsing stages. So the
trick is to use a normal GString not a slashy string:

def var = "c:\\uabc.txt"

Cheers, Paul.
