Helly everyoneFollowing our system settings:osTicket-Version: v1.10Server-Software: Microsoft-IIS/8.5MySQL-Version: 5.7.17PHP-Version: 7.0.9Language -Package: GermanOur problem is that, when a costumer with special characters in the e-mail address (for example äü@ö.com) tries to open a new ticket, this e-mail address is not recogniced as a valid e-mail address. Sure I could turn the validator in the forms to "no validator", but I don't think that is a good solution.Is it possible that I can add the characters äöü to the current E-Mail-Adress validator?Thanks in advance for your help.
