How to pass empty string as macro parameter?

For example

!macro TestMacro param1 param2

  Push param1

  Push param2

!macroend



!insertmacro TestMacro "" "test"

this code raises an error - Push expects 1 parameters, got 0. It happens because param1 is replaced by nothing, in result we have Push call without any parameters. How do you resolve this problem?

!macro TestMacro param1 param2

  Push `${param1}`

  Push `${param2}`

!macroend

Use quotes around the values (` is recommended because ' and " are more commonly used within strings).
