Problem Cause

Known issue with VMware:
The VMware vCenter Server and ESX/ESXi Server do not escape special characters used in the display names.
For example, if a virtual machine name contains the % character, it does not escape the character. This causes issues when querying for the name from vSphere Web Client or using the SDK.

Citrix uses the VMWare SDK on the Delivery Controller or Cloud Connector, via the VMWare Factory plugin, so Citrix will be affected by the limitations as well. 

This issue is seen when special characters like %, &, *, $, #, @, !, \, /, :, *, ?, ", <, >, |, ;, ' etc are contained in names of vSphere entities like virtual machine name, cluster name, datastore/folder/file name, the Domain organizational unit, etc.

Errors are sometimes generated when a special character is used in the creating an MCS machine catalog
