Note also that a single backslash followed by a newline is interpreted as those two characters as part of the string, \emph{not} as a line continuation. +When an `r' or `R' prefix is used in conjunction with a `u' or `U' +prefix, then the \uXXXX escape sequence is processed while \emph{all other +backslashes are left in the string}. For example, the string literal +\code{ur"\u0062\n"} consists of three Unicode characters: +`LATIN SMALL LETTER B', `REVERSE SOLIDUS', and `LATIN SMALL LETTER N'. +Backslashes can be escaped with a preceding backslash; however, both +remain in the string.
