In this configuration, I cannot redirect any output data to a file.
 
Flush() after print() or echo() takes no effect.
Only when 'output_handler' is set to 'mb_output_handler'.


Reproduce code:
---------------
$ cat redirect_test.php
#!/usr/local/bin/php -q
<?php
print "Hello, world.\n";
// flush();
?>

Expected result:
----------------
$ ./redirect_test.php > result.txt
$ ls -l result.txt
-rw-r--r--  1 jkawa  jkawa  14 Sep 12 06:32 result.txt
$ cat result.txt
Hello, world.
$

Actual result:
--------------
$ ls -l result.txt
-rw-r--r--  1 jkawa  jkawa   0 Sep 12 06:40 result.txt
$ cat result.txt
$

can't reproduce it.
check if mbstring module is enabled and your code outputs anything without redirection.
 [2004-09-12 09:20 UTC] jkawa at m dot email dot ne dot jp
Without redirection:
$ redirect_test.php
Hello, world.
$

This seems OK.
But in Japanese (EUC-JP), I got incorrect output.
"incorrect" means something wrong, but without redirection and pipe to other, I could not look into this problem further.

P.S.
According to the output from phpinfo(), mbstring extension is certainly enabled.
 [2004-09-12 09:29 UTC] tony2001@php.net
Does it work for you without output_handler = mb_output_handler ?
 [2004-09-12 11:49 UTC] jkawa at m dot email dot ne dot jp
correction:
Without redirection, everything (including Japanese handling) seems OK even if output_hander set to 'mb_output_handler'.

reply:
Without 'output_handler = mb_output_handler', all but auto code conversion works fine.
