Is there a symbol or character to sort files alphabetically after Z?

We have a ton of clients in our team folder structure in Figma so sorting alphabetically is the easiest way to traverse. We also have a few folders that aren’t client specific (team things, testing area) and are named things like ~ Test (Don’t Use) ~, but these folders still appear first alphabetically.

Is there any symbol or character in Figma file sorting that registers after Z?
