This seems to be a bug in gcj 3.3.2 which only occurs on Solaris 8. I
don't think it happened on Solaris 7 (though I can't verify that any
more) and it doesn't happen on Linux. I don't have access to any other
systems that I can build GCC on.
It also doesn't happen with Sun's java interpreter on Solaris 8.
The problem is that, with a native executable built with gcj, the
first command-line argument is converted to Unicode in such a way that
it starts with a Unicode byte order mark (0xfeff, decimal 65279). This
tends to be confusing for programs that want to do command-line
argument processing, especially for options starting with '-'.
I apologize if this has been reported before, but I couldn't find it
on the bugs database.
Of course, this may well be a Sun bug, but whether they'll be prepared
to fix it for the sake of gcj is another question.
I hope this is enough information. I haven't run the compiler with
-save-temps because there are no include files involved.
Regards,
John Downey

I can't reproduce with GCJ 3.3.2 on Solaris 8:
gax% uname -a
SunOS gax 5.8 Generic_108528-27 sun4u sparc SUNW,Sun-Fire-V250
gax% gcj --encoding=UTF-8 -o pr14722 pr14722.java --main=showargs
gax% ./pr14722 x y z
x (120) y (121) z (122)
gax% ./pr14722 -option
-option (45 111 112 116 105 111 110)
And I can't reproduce on Solaris 7 and 9 either. Which libiconv do you use? If
it's Sun libiconv, I'd tend to think of a Sun bug.

Subject: Re: Bug in conversion to Unicode of command line
arguments
Thanks for your reply.
on Solaris 8, the iconv family of routines appear to be in
/usr/lib/libc.a and /usr/lib/libc.so.1. I can't find a libiconv*
anywhere on this system.
So should I get a separate version of libiconv, from GNU or somewhere?
If so, maybe this should be listed as a prerequisite for using gcj on
Solaris?
Regards,
John Downey

No, I think it's a Sun bug. You might want to see if there isn't a Solaris 8
patch for iconv and UTF-8. We know of related problems on Solaris 7 that appear
to be fixed by
Patch-ID# 112689-02
Synopsis: SunOS 5.7: UTF-8 locale ICONV patch
Also note that you use a GNU binutils version known to be buggy, see
http://gcc.gnu.org/install/specific.html#*-*-solaris2*
