  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.  As a result, \uXXXX escape sequences are
+ only recognized when there are an odd number of backslashes.
