6.6.4 UPNQR (Univerzalnega Plačilnega Naloga QR)
------------------------------------------------
A variation of QR Code used by Združenje Bank Slovenije (Bank Association of
Slovenia). The size, error correction level and ECI are set by Zint and do not
need to be specified. UPNQR is unusual in that it uses ISO-8859-2 formatted data.
Zint will accept UTF-8 data and convert it to ISO-8859-2, or if your data is
already ISO-8859-2 formatted use the --binary switch or if using the API set
symbol->input_mode = DATA MODE;
The following example creates a symbol from data saved as an ISO-8859-2 file:
