We have encountered a serious issue in ET/ETP. When adding (or editing) a ticket (RSVP or WooCommerce-based), and entering international characters in the name or description fields for a ticket, the ticket is not saved when pressing the Save Ticket button.
The issue is also observed when using other special characters in the name/description fields, like “%”, “#” and “&”. We do not usually use these characters for ticket name/description text, but these should not cause problems if used.
When deleting the international characters from the name/description fields, the ticket is saved correctly.
As our site uses the Swedish language, we need to be able to use international characters for our tickets. Previously, we have been able to use international characters for tickets.
We tested on different browsers (current Safari and Chrome), and on two different installations of the same web, and the issue remains. Also, all other plugins are deactivated, and the default Twenty-Sixteen theme was used during testing.
