    Call language logic in default script's sayLine()
    
    This is another change that should not impact the end-user experience.
    It is a precursor to implementing support for on-the-fly language
    switching.
    
    Also add a debugging line so we can identify any apps or toolkits for
    which getting text attributes is non-performant.
