 New Comment:

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation
better.

"Some systems (like IBM AIX) use "ISO8859-1" instead of "ISO-8859-1" so
this value has to be used in configuration options and function
parameters."

Hello sniper!

I agree with you (and understand if you'd rather not "patch" for this),
although these kind of quirks seem to appear all the time with OSes from
the "big" companies... :-/

In any case, it may be worth pointing out in the documentation, at
least, so that people will be aware of this difference.

Thanks in advance!

Best regards,
Bj�rn

It's pretty idiotic by IBM to do that. Why not tell them to fix their
crap?

Perhaps it would be possible to make sure that php.ini-dist and
php.ini-recommended (and the default values in PHP, for the situation
where no php.ini is found) get modified on AIX upon ./configure,
testing or installation, unless GNU libiconv is found?

php -i reports the following under AIX by default (no php.ini is in
place here so the local and master values are equal).

Description:
------------
Under IBM AIX, using the IBM-shipped version of libiconv (package
bos.rte.iconv) requires one to use "ISO8859-1" instead of "ISO-8859-1"
in the call to iconv() when dealing with ISO latin-1 character set
conversions.

Probably one should set iconv.input_encoding, iconv.internal_encoding
and iconv.output_encoding to "ISO8859-1" as well, in php.ini or the
Apache server configuration (to override the default values of
"ISO-8859-1").

Other similar cases seem to be present, see:
http://publibn.boulder.ibm.com/doc_link/en_US/a_doc_lib/aixprggd/genprogc/convert_prg.htm#HD
RDNNRI49HOWA

This may be worth to point out in the PHP iconv documentation:
http://www.php.net/iconv

Furthermore, this may very well be the cause for the iconv tests
failing under AIX.


Reproduce code:
---------------
The package origin of the libiconv.a file is given by:

$ lslpp -w /usr/lib/libiconv.a 
  File                                        Fileset              
Type
 
----------------------------------------------------------------------------
  /usr/lib/libiconv.a                         bos.rte.iconv        
File


Version information is given by:

$ lslpp -la | grep iconv
  bos.iconv.com              5.2.0.0  COMMITTED  Common Language to
Language
  bos.iconv.ucs.com          5.2.0.0  COMMITTED  Unicode Base
Converters for
  bos.rte.iconv              5.2.0.0  COMMITTED  Language Converters


Working PHP code for translating some Swedish characters in character
set ISO8859-1 to UTF-8:

<?php
  if (function_exists('iconv')) {
                                $namn = iconv('ISO8859-1', 'UTF-8',
"åäö");
                                echo "Result: $namn";
  }
?> 

Using "ISO-8859-1" does not work!


Excerpt from 'make test':

Actual result:
--------------
iconv() returning FALSE when the conversion fails (due to "incorrect"
encoding specified).
