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"))]'

This is strange ,do not understand why you can run it ok but when I run it I get:
3/10/2023 11:52:52 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

The second parameter in Input window is:
'[vbld_EscapeString(vbld_AllMacros()("MyParam2"))]'

Maybe I have some options activated you do not have?
Or maybe could you please try to run in in VBP 9.7 (same version as me )?

I get the same result as you in v9.7.
