Authorize.net Integration: Does the integration accept special characters on payment info?

Heya. I work for a non-profit that accepts all of our donations and payments currently through Authorize.net integrated into a wufoo form. We work with a lot of europeans and other nationalities, and we currently have a problem. We offer recurring monthly donations on the 5th or 20th of the month. And the batch on the 20th sits "Pending" in donors bank accounts for about a month before being dropped, while the reports we get from Authorize and our other services show we have the money. Long story short, Authorize and our other services say that it's because Wufoo is allowing non-english characters in the payment details (addresses, names, .etc) so we end up with things like the umlaut .etc

After talking with Wufoo customer service, it seems that prohibiting non-english characters is not an option, so we are looking to a new service. I know Jotform works with Authorize, but if we move to Jotform, will I be able to set it up to reject these non-english characters?

JotForm is designed to work on multiple languages, although I'm not totally sure what do your refer with non-English characters, I have not seen reports about this. 

Could you please provide us some examples about the payment info with non-English characters? 

I would suggest you to give it a try, create a form and then add the Authorize.net integration to your form and then try adding those characters. 

We will make some tests as well on our end, here is a guide that will help you to test your integration:
