UCCX: How to remove a language directory with special characters in Prompt Management?

Hi,

In UCCX 10.6.1.10000-39

Applications / Prompt Management I have a directory with special characters that I would like to delete. When I try to delete the directory I get :

Access Denied

Unified CCX does not allow special characters because security protocols restrict their use. Click the Back button in the browser to perform configuration

Do I really open a tacl to this ???
