![]() ![]() ![]() Using a 2D barcode symbology like Aztec or Datamatrix with dedicated support for non-ASCII data might be a better choice. However, this feature is not widely supported. ÃÃÃ) can be encoded in a Code 128 symbol by using a special character (FNC4). In principle non-ASCII characters like German umlauts (e.g. ^ 'ISO/IEC 15417:2007 - Information technology - Automatic identification and data capture techniques - Code 128 bar code symbology specification'.The optimal encoding can be found using a dynamic programming algorithm. Reporting just the lengths of each run gives 1, 1, 1, 3, 2, 3, thereby producing a widths value of 111323. For example, using the pattern 10100011000, the run lengths are 1 (digit 1), 1 (digit 0), 1 (digit 1), 3 (digit 0), 2 (digit 1), 3 (digit 0). ![]() There will always be 6 runs and the lengths of these 6 runs form the Widths value. The widths value is derived by counting the length of each run of 1's then 0's in the pattern, starting from the left. ![]()
