Just a quick note that may be helpful for some:

It seems to me that this function also modifies the HTTP Content-Type header that's sent to the client (at least in combination with the iconv_set_encoding() function).



If you specify an encoding ending with "//TRANSLIT" or "//IGNORE" (valid in iconv), it will still send the encoding name in the HTTP header. This makes it an invalid character set unfortunately.



For example:

<?php

iconv_set_encoding("internal_encoding","UTF-8");

iconv_set_encoding("output_encoding","ISO-8859-1//TRANSLIT");

ob_start("ob_iconv_handler");

?>

will send a Content-Type header of "ISO-8859-1//TRANSLIT".
