Don't forget that your pattern is scanned first by the C++ compiler. In
this case, this means that \0x21 is never seen by the RegExp engine;
instead, it sees a NUL character (ASCII 0) followed by "x21". NUL is not
valid in any pattern and thus an exception is thrown. Use double
backslashes to get a backslash through to the engine.
