In my grammar for lexpjs (an expression language I wrote and use in various contexts), I need to allow Unicode characters in identifiers (variable and function names). As presented, jison-lex 0.3.4 does not have support for RegExp Unicode property escapes in patterns in the source grammar. This change detects the use of a Unicode property escape in a pattern and adds the "u" flag to the compilation of the pattern to make them function correctly.
