I have a hexadecimal string representation of a Unicode codepoint:

    my $unicode_character_hexadecimal_string = '0x20ac';

[download]
First, I want to convert this hexadecimal string representation of a Unicode codepoint to an integer. Easy enough:

    my $unicode_codepoint_integer
        = eval $unicode_character_hexadecimal_string;

[download]
Right?

From here, I want to get to some hexadecimal string representation of the UTF-8 encoding of this Unicode codepoint:

    '0xE2 0x82 0xAC'

[download]
or perhaps simply

    'E2 82 AC'

[download]
Then, as strange as it seems, I want to get to an analagous hexadecimal string representation of the same sequence of bytes with the most significant bit turned off (i.e, with 0x80 substracted):

    '0x62 0x02 0x2C'

[download]
or

    '62 02 2C'

[download]
Oh, and along the way, I also want to get binary string representations of the same values:

    '11100010 10000010 10101100'

[download]
and 
    '01100010 00000010 00101100'

[download]
Finally, I want to print the Unicode (UTF-8) characters alongside these various string representations.

I'm trying to generate a kind of metavalue table. You have to trust me: I really do want to do exactly what I've outlined above. I'm using Perl 5.8.8 (ActivePerl build 822).

Thanks.

Jim
