Run Powershell script with parameters containing special chars

[teognost]

I am using VBP 9.7 but I think it does not make any difference.
Did you try to copy the Test.ps1 attached in a message above to the VBP folder(%PROJDIR%)?
I get the error when running first step"Run Test PowerShell script-with parameters" which is running %PROJDIR%\Test.ps1 with 2 Input params :
%MyParam1%
'[vbld_EscapeString(vbld_AllMacros()("MyParam2"))]'

The step "Run PowerShell script from batch step" is running ok as I put there the command with Param2 enclosed with' :
C:\Windows\System32\WindowsPowerShell\v1.0\powersh ell.exe -nologo -noninteractive -executionpolicy Unrestricted "& '%PROJDIR%\Test.ps1' -Param1 '%MyParam1%' -Param2 '[vbld_EscapeString(vbld_AllMacros()("MyParam2"))]'
