    Preload UTF-8 encoding module
    After review, Alex pointed out that the root error was Encode::encode
    failing to load the encoding due to internal state problems in perl.
    This patch pre-loads the encoding before setting up the sig __WARN__
    handler.  This will avoid the Encode failing to load.  It should
    be noted that Carp.pm too needs to be preloaded or it too can fail
    at runtime inside of Encode::encode.
    Lastly, because Encode::encode is called without checking enabled,
    any UTF-8 strict encoding errors are discarded as warnings are disabled
    and the encoding warnings are themselves reissued witha
    warnings::warnif. If the encoding warnings need to be debuged the
    check paramter Encode::LEAVE_SRC should be passed to Encode::encode.
    This will then log the original message.  This might be a useful debug
    Fixes: I#32648
