Thank you for your prompt assistance ulfben.
I’ve tried that version you linked to and it now displays the symbol correctly in all but one of my categories. I believe that’s because it is being cut off by the “Characters to display.” It shows as “Computers &am…” Please see: https://www.newdealfinder.com/
Additionally the entire category tree doesn’t display when viewed on some category pages. Example: https://www.newdealfinder.com/category/categories/computers-and-office/
Firebug says, “unterminated string literal
[Break on this error] c.openTo(‘Office”, true);\n”
