Version 8.1.1.7 of the Softek Barcode Reader Toolkit for Windows has been released. This version addresses an issue with handling UTF-8 encoded data in a PDF-417 or DataMatrix bar code.<\/p>\n
The problem…<\/p>\n
Say you have a PDF417 bar code that encodes the characters:<\/p>\n
\u30ad\u30e4\u30ce\u30f3\u96fb\u5b50<\/p>\n
….in UTF-8 format with the following bytes of hex data:<\/p>\n
E3 82 AD E3 83 A4 E3 83 8E E3 83 B3 E9 9B BB E5 AD 90<\/p>\n
In previous versions of the SDK this would display as:<\/p>\n
=E3=82=AD=E3=83=A4=E3=83=8E=E3=83=B3=E9=9B=BB=E5=AD=90<\/p>\n
…with Encoding set to 1 (quoted printable), which is correct.<\/p>\n
But with Encoding set to 3 (UTF-8) the data is double encoded and displays as:<\/p>\n
\u00e3\u0082\u00ad\u00e3\u0083\u00a4\u00e3\u0083\u008e\u00e3\u0083<\/p>\n
…and contains the following bytes of hex data:<\/p>\n
C3 A3 C2 82 C2 AD C3 A3 C2 83 C2 A4 C3 A3 C2 83 C2 8E C3 A3 C2 83 C2 B3 C3 A9 C2 9B C2 BB C3 A5 C2 AD C2 90<\/p>\n
Version 8.1.1.7 checks the binary data (with reference to the property Pdf417AutoUTF8) to see if it is already encoded as UTF8 and if so does not encode it again.<\/p>\n
Note that it is quite possible that binary data in a PDF417 bar code could look like UTF-8 encoded data but the requirement is to allow it to pass through. In this case the Pdf417AutoUTF8 setting should be disabled.<\/p>\n
The same applies to DataMatrix bar codes and the property called DataMatrixAutoUTF8<\/p>\n
