There is a data corruption when generating a barcode.
Just save the example, and open it in a browser.

The generated barcode text should be:

But it's:

Hrvatski dijakritički znakovi ne rade
Hvala na generatoru. :)
Na žalost ne radi kako treba ako ime, naziv ili adresa sadrže Hrvatske dijakritičke znakove. Ima li neki fix kako omogućiti da se generiraju ispravno?
