It's a nice presentation, but the QR-code builder doesn't understand Kanji or Alphanumeric (5.5 bit / symbol) encoding. It does, however, look very, very nice.

It's a nice presentation, but the QR-code builder doesn't understand Kanji or Alphanumeric (5.5 bit / symbol) encoding. It does, however, look very, very nice. I'm not complaining too much, just suggesting the authors encode alphanumeric data with the lower bit per symbol encoding when appropriate.
