Description of problem:
This happens for many encodings but the test case uses ISO-
10646/UCS2/. When converting from UCS4-LE to ISO-10646/UCS2/ iconv 
consumes certain characters without producing anything in the output 
buffer and also without giving any errors. This happens for example 
for characters 0xE0000 to 0xE007F.

Please see the attached C program:

#include <stdio.h>
#include <wchar.h>
#include <iconv.h>

int main()
{
  wchar_t inbuf[16] = { 0xE0000, 0, };
  char outbuf[16] = { 0, };
  char *in_ptr = (char *) inbuf;
  size_t in_size = sizeof(wchar_t);
  char *out_ptr = outbuf;
  size_t out_size = sizeof outbuf;
  iconv_t enc = iconv_open("ISO-10646/UCS2/", "UCS-4LE");
  int n = iconv(enc, &in_ptr, &in_size, &out_ptr, &out_size);
  printf("n = %d  in_size = %d  out_size = %d\n", n, in_size, 
out_size);

  iconv_close(enc);
  return 0;
}


Version-Release number of selected component (if applicable):
glibc-2.3.3-27

How reproducible:
Always

Steps to Reproduce:
1. gcc -o iconv_bug2 iconv_bug2.c
2. ./iconv_bug2

    

Actual Results:  n = 0  in_size = 0  out_size = 16

Expected Results:  Depending on the encoding, either an error (n = -
1) or some output produced (out_size < 16).
