029-string-escapes.M1pp (660B)

      1 # String escape decoding at emission.
      2 #  - In the lexer, `\X` inside a STRING is one unit (so `\"` and `\\`
      3 #    do NOT terminate the literal), but the byte value is left for the
      4 #    emitter to decode.
      5 #  - At output, `\\` becomes `5C`, `\"` becomes `22`, etc. — the same
      6 #    table used to live behind `%bytes(...)` and now applies to every
      7 #    bare string token.
      8 #  - Both quote styles ("..." and '...') participate.
