Wrong image path for section with no-latin chars in the alias
When section have alias containing non-latin chars in the alias like Hotelführer, then path used for storing qr-code image remove the non-latin character, but when image is loaded on the front-end, such character is used. So image is stored in the folder:
/images/sobipro/qrcodes/Hotelfhrer/
but on the front-end is requested path:
/images/sobipro/qrcodes/Hotelführer/
In the result qr-code image is not visible.
