Hi everyone

I've got a form with a text field which its label is: "Nº de vuelo¨. When the form is submitted, the email workflow fails with the following error:

2017-04-11 14:12:00,772 [9] ERROR Umbraco.Forms.Core.Providers.WorkflowTypes.SendEmail - [Thread 24] There was a problem sending an email to 'EMAIL_ADDRESS' from Workflow for Form 'Transfers' with id '292a15df-09c3-4365-82f8-a188abd361b5' for Record with unique id '0137e7be-43ba-44ee-a55c-127c018b4480'

Is there anything I should do to be able to use that character or is this a bug?

Cheers!
