Search builder stops working after 5.3.1 (due accents on custom set fields titles)
After 5.3.1 upgrade Search Builder jQuery interaction stops working. I could find the reason, seems that custom set title with accents break the Search Builder form.
How to test? On dmaster go to https://dmaster.demo.civicrm.org/civicrm/admin/custom/group?reset=1 and edit a custom set title for example with "Cancelación Suscripción" and save it. Then go to https://dmaster.demo.civicrm.org/civicrm/contact/search/builder?reset=1 and select some -record type- you will notice that no type of operator related to the selected type is suggested.
On the browser console appears this error:
