multibyte emulation

gnutella 0.6 protocol can only handles iso-latin-1 encoding in search and search result.

i think an option should be added
emulate multibyte mode.

convert multibyte (utf-8) to non-lossy-ascii (is compatible with iso-latin-1)
and search.

convert non-lossy-ascii to utf-8 (alphabet would be passed)
and display search result.

thanks.

Non-Lossy-ASCII means ESCAPE UNICODE.
This code is used in Java's localization.
And it's effective to handle.
