Posting because someone else will likely end up here looking for help trying to create a SymbolicLink with PowerShell in combination with CimFS volumes or similar with funky 🕺 characters
The PowerShell command New-Item -Type SymbolicLink can not handle a path with a "?". You need to escape the "?" for the command to work correctly.
Example, note the backtick before the "?", apparently called a grave 🪦 as well - learnt something new.
New-Item -Type SymbolicLink -Path "C:\temp\ThisIsTheSymbolicLink" -Target '\\`?\Volume{5dc22e05-95f4-4993-9591-c0e187b0356d}\'
