gpg: conversion from `utf-8' to `CP437' not available (WinXP)

[david atlan (PHENO)]

Hi,

I am new to Gnupg, I have downloaded gnupg-w32cli-1.4.0a.zip and verified  
the checksum. I have created a directory as indicated in the manual and  
copied the gpg.exe file and launched it from the dos command line:

C:\gnupg>gpg
gpg: conversion from `utf-8' to `CP437' not available

did I miss something somewhere???

Merry christmas and happy new year,

David
