UCCX: How do I 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 configure the settings

Do I really need to start a thread about this???
