[PATCH] Use perl builtin class utf8 for UTF-8 decoding

["Ismail Dönmez" <ismail@pardus.org.tr>]

Junio it would be very nice to get this in 1.5.4, fixes multiple problems and 
tested with many distros with success.

Use perl builtin class utf8 for UTF-8 decoding, this fixes Encode problems 
with older Encode and avoids problems on UTF-8 locales.
