Hello,

I need a piece of comment about PDF417 specification. Suppose I am in Text Alpha mode and I  see the following succession of symbols:

29 913 0 0

so i have to interpret that succession in this way:

<text "A"> <shift to punctuation mode> <shift to byte mode> <byte "0"> ... 

then the first symbol after we returned from byte mode is 0. But did we returned from the shift to punctuation? Should we interpret the first part of the fourth symbol as a punctuation (":"), or as an alpha mode ("A") ? So is thу following ":A" or "AA"?
