jQuery Grid Plugin - jqGrid

Hi all, I am new to the forum...Hello! to everyone!. Can someone PLEASE offer staightforward guidelines/instructions to get subgrids to render properly when the id/foreign key contains special characters? I have found other posts on this subject in this forum and I have tried all of their suggestions, but still no luck. I have been stuck for many hours 🙁 Any assistance would be much appreciated.

I am working with subgrids within a grid - ie. subGridRowExpanded:....

The subgrids and their data display fine for rows where the id/foreign key does NOT contain special characters. If the key DOES contain special characters, the subgrid will not even render when the master record row is expanded.

Thanks!
