            Bug ID: 17610
           Summary: iconv fails converting 0xCC in EBCDIC-AT-DE chars
           Product: glibc
           Version: 2.19
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org

Hallo,

while converting RPG scripts from an IBM's iSeries I found a converting error.

See the following Base64-encoded line from an RPG script with EBCDIC 1141 
charset:

QEBAQEBAXMSBo6SUQEBAQEBAzEDBpKOWmUBAQEBAQEBAQEBAzE
DChaKDiJmFiYKklYdAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBA
QEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQA==

In ISO-8859-1 this reads:

      *Datum      ¦ Autor           ¦ Beschreibung 

But iconv (Version "(Ubuntu EGLIBC 2.19-0ubuntu6.3) 2.19") fails to convert ¦ 
from EBCDIC 1141 (0xCC) to ISO-8859-1 (0xA6):

$ echo QEBAQEBAXMSBo6SUQEBAQEBAzEDBpKOWmUBAQEBAQEBAQEBAzE\
DChaKDiJmFiYKklYdAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBA\
QEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQA== | base64 -d | 
iconv -f EBCDIC-AT-DE -t ISO-8859-1
      *Datum      iconv: illegal input sequence at position 18

Other characters like 0xBB (|) or 0xBF (×) aren't converted, either.

Best regards,

Roland Tapken

You are copying between overlapping objects, which is undefined behaviour.  The
same is true for memcpy.

EBCDIC-AT-DE implements CP8, not CP1141.
