#2457 unmappable character for encoding UTF8

[NJ]

Compiling with
java version "1.6.0_18"
OpenJDK Runtime Environment (IcedTea6 1.8) (6b18-1.8-0ubuntu2)
gave many warnings like:

[javac] /gallery_remote/HTTPClient/HTTPConnection.java:5: warning: unmappable character for encoding UTF8
[javac] * Copyright (C) 1996-2001 Ronald Tschal�r

This obscures other warnings, if there are any.
