Emoji characters for food allergens

[William_J_G Overington]

Hi Marcel
> Alternately, scanning the EAN barcode on the package could give access to a database intended for food information. This requires the use of a smartphone or other compatible device.
That is a good idea.
In which case the emoji would not need to be encoded on the package, yet would be sent by the database facility. Using EAN barcode to database and the results sent to the end user would need a two-way communication link and that could possibly mean queueing problems as the database facility would possibly be answering requests from many people.
Another possibility would be to encode the Unicode characters for the allergens contained in the food within a QR code (Quick Response Code) on the package.
Decoding could then be local, in the device being used to scan the QR code.
Both of these methods, EAN barcode and QR code, could be used to communicate through the language barrier, either by viewing the emoji, or by the emoji becoming converted to localized text in the device that is being used by the end user.
Best regards,
