in thread binary parsing

It seems that the output is different on an Win32 XP system...

perl -le"print length unpack "A", "\n";" 1
Could you please direct me in which side of the documentation neighborhood that this is reported ?

    Your quoting is broken. You are doing

    >perl -le"print length unpack 'A', \'n';" 1

    which is the same as

    >perl -le"print length unpack 'A', 'S';" 1

    If you fix the quoting, you get the correct result.

    >perl -le"print length unpack 'A', qq{\n};" 0

    pack says "When unpacking, «A» strips trailing whitespace and nulls".
