contains a backslash
Script parsing fails when the string contains a backslash

keep;
stop;
}

Does it work with this rule? :
if allof (header :contains "to" "\\\\") {
Thx,

---------------------------------------------
I've added a test case (main/src/test/java/org/apache/jsieve/LiteralEscapeTest.java) but don't seem to be able to reproduce the problem. i have some vague memory of fixing an escaping bug so it could already be fixed.
Boris - could you check that the test case is correct and - if so - whether this issue is reproduceable using the latest code.
Cheers
Robert

Norman Maurer commented on JSIEVE-74:
-------------------------------------
Just for the record, here is the rfc part which is relevant to this buf:
A quoted string starts and ends with a single double quote (the <">
character, ASCII 34). A backslash ("\", ASCII 92) inside of a quoted
string is followed by either another backslash or a double quote.
This two-character sequence represents a single backslash or double-
quote within the string, respectively.
