  I think there's another issue in the handling of strings.

  The spec says that valid unescaped chars are in the following range:

     unescaped = %x20-21 / %x23-5B / %x5D-10FFFF

  But we do:

     [IN_DQ_STRING] = {
         [1 ... 0xFF] = IN_DQ_STRING,
         ['\\'] = IN_DQ_STRING_ESCAPE,
         ['"'] = IN_DONE_STRING,
     },

  Shouldn't we cover 0x20 .. 0xFF instead?

If it's the lexer, isn't just it being liberal in what it accepts?
