iconv on Solaris

Mon Sep 24 01:34:00 GMT 2001

Is it a known problem that things like BufferedReader do not
work on Solaris 2.8?
The problem is that libjava uses iconv on Solaris, converting from
646 to UCS-2. Unfortunately, the Solaris iconv for this case seems
to be broken. Here is an (ugly) test program:
#include <stdio.h>
#include <iconv.h>
int main () {
 char input[12];
 char output[12];
 size_t inbytes = 1;
 size_t outbytes = 12;
 iconv_t cd;
 const char *ic = input;
 char *oc = output;
 int r;
 input[0] = ' ';
 output[0] = output[1] = 0;
 fprintf (stderr, "%x %x\n", ic, oc);
 cd = iconv_open ("UCS-2", "646");
 r = iconv(cd, &ic, &inbytes, &oc, &outbytes);
 fprintf (stderr, "%x %x\n", ic, oc);
 fprintf (stderr, "%d %d %d %d %d\n", r, output[0], output[1],
	 output[2], output[3]);
}
The output of this program is:
gcc test.c && ./a.out
ffbef900 ffbef8f0
ffbef901 ffbef8f4
0 -2 -1 0 32
Note that there are 4 bytes of output, even though we converted one
byte of 646 to UCS-2. Using UCS-2BE or UCS-2LE yields sensible
output; it seems that perhaps we should use one of those on Solaris?
Or am I crazy? (I am not smart about internationalization...)
