not sure if better...

but just some other ways to do it :)

1> A="This is some\\r\\ntext".
"This is some\\r\\ntext"
2> re:replace(A,"\\\\r\\\\n","\r\n",[{return,list}, global, unicode]).
"This is some\r\ntext"

or

1> A = "This is some\\r\\ntext".
"This is some\\r\\ntext"
2>     [C,D] = string:tokens(A,"\\r\\n").
["This is some","text"]
3>     C ++ "\r\n" ++ D.
"This is some\r\ntext"
