* Replacing non ISO-8859-1 characters in input with '?' when neither a character set nor multi-eci encoding is selected.
* Changed code to raise an exception for characters not encodeable in ISO-8859-1
* - Added multi-eci decoding for PDF417
- Fixed issue that some multi-eci encoded PDF417 codes were missing ECIs
* Syntactic changes
* - Fixed issue that ECIs were not processed correctly in all allowed locations in binary encoded data as specified in section 5.5.3.2 of the spec
- Added verifying unit test
* - Added multi-eci encoding for PDF417
- Fixed issue that the PDF417 decoder incorrectly decoded input with a leading ECI and no explicit latch to TEXT encoding
* Added support for multiple character-ECIs
* - Changed from ArrayList<Byte> to ByteArrayOutputStream
- Added blank lines
* Improved performance for the general case (without ECI)
Quote of Martin's proposed changes to the spec:
The algorithm can be salvaged to be at least sound by making those changes, e.g. by adding to step e):
"1) If the next character cannot be encoded as X12, switch to ASCII mode and go to step b)."
(and renumbering the following sub-steps). Similarly step f):
"1) If the next character cannot be encoded as EDIFACT, switch to ASCII mode and go to step b)."
