Re: Incorrect IBM870 charmap

[Karel Tomas]

Hello.

The patch is right, but it is reversed.
Here is a part from the file before application of the patch, which, as you
can see, is not correct.

<U00B6>     /xb6         PILCROW SIGN
<U017E>     /xb7         LATIN SMALL LETTER Z WITH CARON
<U017A>     /xb8         LATIN SMALL LETTER Z WITH ACUTE
<U017D>     /xb9         LATIN CAPITAL LETTER Z WITH CARON
<U0179>     /xba         LATIN CAPITAL LETTER Z WITH ACUTE


The problem itself was corrected very nearly after my submission of this
bug,
In the time, I reported problem, I have had used RedHat version 7 which had
included incorrect version of the file
glibc-2.2.4/localedata/charmaps/IBM870.
When Redhat 8.0 was released, mentioned codepage was corrected, and trouble
was away.
So for now I think there is no need to apply the patch, I have sent you
earlier.

Best regards Karel Tomas

Hi.  I guess no-one gave you an answer to your request.  I'm looking
at unhandled locale errors, and found yours.

Are you sure this patch is correct.  On the URL given above, I find
<URL:
http://www-1.ibm.com/servers/eserver/iseries/software/globalization/pdf/cp00870z.pdf
>
for the IBM CP870.  This document lists LATIN SMALL LETTER Z WITH
CARON for 0xb6, and LATIN CAPITAL LETTER L WITH STROKE for 0xba (and
the rest match the original file as well).  It seem to me that the
glibc definition for IBM870 is correct.  Your conversion problem must
have another explanation.
