Can't write non english characters in labels - Community / Bug Report - Deskpro Support
Please check the settings for the label name field on /admin/settings/labels/tickets page. I would like to use hungarian characters like öüóőúéáűíÖÜÓŐÚÉÁŰÍ but it's impossible because they are not letters. :-)
This should definitely be possible; we are working on this.
This has been fixed for our next update. This was a bug in the admin management page, everywhere else will allow any input (e.g., enter a label from agent ticket view).
