#12602: C++11 raw string literals with embedded escapes are mislexed

 Reporter:  edaskel@…         |      Owner:  hkaiser
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  wave
  Version:  Boost 1.63.0      |   Severity:  Problem

------------------------------+---------------------
 Raw string literals are partly intended to make it easier to write strings
 that would otherwise require extensive escaping - e.g., regular
 expressions.  Unfortunately Wave seems to get confused when backslashes
 appear in C++11 raw string literals.  For example:

 R"(A\+)"

 is parsed by compilers as a string of three characters: A, backslash, and
 +.  Wave lexes this as an unterminated raw string literal followed by six
 individual character tokens.  By contrast:

 R"(A+)"

 is correctly parsed as a two-character raw string literal.
