Encode problems?

[Sharky @ PTNet]

Hi all,
I have installed gpg in my Windows XP box (at work) and trying to decrypt
some file have this error:

"""
gpg: conversion from `utf-8' to `CP437' failed: Illegal byte sequence
gpg: decifragem falhou: chave secreta nπo disponφvel
"""

How can I resolve this? :-P

Many thanks for all,
Sharky @ PTNet
