Added a warning that these scripts leak information.

Ensure it's abundently clear that these scripts may be bad news with stupid-assed clients which contravine their prime directives, such as content-type, or do not harm humans. Flaws such as utf-7 decoding ensure that even txt->html transforms are insufficient.

Add charset to the painfully old example scripts. These should really be replaced with proper encoding of the output.
