Xojo’s inability to handle Kanji code in QRcode generation and scanning is a fatal flaw.
Consider Shift-JIS or UTF-8.
Providing Kanji code to Xojo’s Barcode.Imagen will result in an invalidargumentException.
→ Barcode could not be created with the supplied inputs.
Please correctly handle ISO18004 Chapter 7, 7.3.6 Kanji mode.
