@str("[brackets]") not showing / Bug or intended?

Hello everyone,

working in Smart Templates, I cannot get @str to output [square brackets].

@str(“[Date]”)

outputs “Date” instead of “[Date]” - however, using

@date-var: @format-date(@date-var, “dotted-dd-mm-yyyy”) | else: [Date]

will output “[Date]” if the @date-var is undefined.

Is there a reason @str(“[]”) does not work?
