Nevermind, in windows the EXIF module isn't compiled with MBSTRING
support.

Thanks for the comments.
I've updated my code according to Pierre's suggestion:

ini_set('exif.decode_unicode_intel', 'UCS-2LE');
ini_set('exif.encode_unicode','ISO-8859-1');
ini_set('exif.encode_jis','ISO-8859-1');
ini_set('exif.decode_jis_intel','ISO-8859-1');
$arrComment = exif_read_data('1.jpg', 'WINXP', true);

The problem still exists (Only first letter is returned).

Here's the example file:

Loading the mbstring extension is one of the requirement, another is to
specify the encoding (See http://de.php.net/exif) using either php.ini
or ini_set.

If the problem remains, please provide a link to the image  as
requested by Sniper.

Put that image file somewhere where we can download it and try
ourselves.

Description:
------------
I'm trying to extract EXIF information created by the Windows XP
Explorer (In particular the Comments field).

Dumping the array created by

exif_read_data('c:\test.jpg','WINXP',true);

includes the following result:

["WINXP"]=>
  array(1) {
    ["Comments"]=>
    string(1) "G"
  }

The problem is that the comment is not only the letter "G",
but a full sentence (starting with G).

Apparently, the comment is UNICODE (UCS-2?). I tried to
use mb_string (Loading php_mbstring.dll before php_exif.dll
like outlined in the PHP manual) without success.

The constant EXIF_USE_MBSTRING is 0 - isn't this a contradiction with
the PHP Manual that says 
"Windows users must also have the  mbstring  extension enabled"?

If this is not a bug, please consider it as a request to
enhance the PHP Manual with a small example showing the
necessary php.ini configurations to use in conjuction with
Windows XP Explorer EXIF comments. Windows Explorer is the
most convenient application for our users to add EXIF comments.

PHP 4.3.10 Zipfile distribution, using the CGI (php.exe).

Reproduce code:
---------------
exif_read_data('c:\test.jpg','WINXP',true);

Expected result:
----------------
["WINXP"]=>
  array(1) {
    ["Comments"]=>
    string(1) "G"
  }

Actual result:
--------------
["WINXP"]=>
  array(1) {
    ["Comments"]=>
    string(1) "Generator and pump"
  }
