Run Powershell script with parameters containing special chars

[teognost]

I have one more issue,if param MyParam2 contains { I got an error at step Run Test PowerShell script-with parameters :

3/8/2023 12:26:39 AM: Building project step 2 - Run Test PowerShell script-with parameters...
C:\Windows\System32\WindowsPowerShell\v1.0\powersh ell.exe -nologo -noninteractive -executionpolicy Unrestricted "& 'C:\Program Files\VisBuildPro9\Test.ps1' Test1 Test{2[]??"
Missing closing '}' in statement block or type definition.
+ CategoryInfo : ParserError: ( : ) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : MissingEndCurlyBrace

This is because the powershell script is launched with parameters without enclosing ' '

For example if I launch the script from a batch file step by adding enclosing ' ' all is ok:

C:\Windows\System32\WindowsPowerShell\v1.0\powersh ell.exe -nologo -noninteractive -executionpolicy Unrestricted "& 'C:\Program Files\VisBuildPro9\Test.ps1' -Param1 'Test1' -Param2 'Test{2[]??'
Param1= Test1
Param2= Test{2[]??

Is there a way to add enclosing ' ' when using a Powershell step?
