Cisco Infrastructure :: UTF 4-8 Encoding Error In UCCX Script

I'm trying to use the IP phone directory xml url in my UCCX script to use for "Calling Name" presentation and the Set enterprise presentation parameter for the CAD where (if found Calling name) it will be presented. This is working, but if the Calling Name includes special characters the script fails with a UTF 4-8 encoding error double byte....bla.  something popup in the script.

Question: is is it possible to handle UTF exceptions in a UCCX script?
