Q: 

Anyone know of the logic to compute the Version of a QR code needed to encode data ?

The spec has 4 of these tables: http://www.denso-wave.com/qrcode/vertable1-e.html

to handle versions 1-40

I'm wondering if anyone has coded something to formulate calculating the version needed for a string of data. None of the libraries I've seen for encoding the data offer this.
