mb_http_output
In response to mortoray at ecircle-ag dot com:
The characters display fine as long as you set the Encoding to something more "Latin 1" compatible (i.e. US-ACSII, ISO-8859-1, ISO-8859-1, or Windows 1252). PHP.net auto-detects to UTF-8
mb_internal_encoding
(PHP 4 >= 4.0.6, PHP 5)
mb_internal_encoding — Set/Get internal character encoding
Description
Set/Get the internal character encoding
Parameters
-
encoding -
encodingis the character encoding name used for the HTTP input character encoding conversion, HTTP output character encoding conversion, and the default character encoding for string functions defined by the mbstring module. You should notice that the internal enconding is totally different from the one for multibyte regex.
Return Values
If encoding is set, then
Returns TRUE on success or FALSE on failure.
In this case, the character encoding for multibyte regex is NOT changed.
If encoding is omitted, then
the current character encoding name is returned.
Examples
Example #1 mb_internal_encoding() example
<?php
/* Set internal character encoding to UTF-8 */
mb_internal_encoding("UTF-8");
/* Display current internal character encoding */
echo mb_internal_encoding();
?>

Be aware that the strings in your source files must match the encoding you specify by mb_internal_encoding. It appears the Parser loads raw bytes from the file and refers to its internal encoding to determine their actual encoding.
To demonstrate, the following outputs as espected when the /source/ file is Latin-1 encoded:
<?php
mb_internal_encoding("iso-8859-1");
mb_http_output( "UTF-8" );
ob_start("mb_output_handler");
echo "üöä<br/>";
?>üöä
Now, a typical use of mb_internal_encoding is shown as follows. Make the change to "utf-8" but leave the /source/ file encoding unchanged:
<?php
mb_internal_encoding("UTF-8");
mb_http_output( "UTF-8" );
ob_start("mb_output_handler");
echo "üöä<br/>";
?>üöä
The output will just show the <br/> tag and no text.
Save the file as UTF-8 encoding and then the results will be as expected.

i noticed that setting mb_internal_encoding('UTF-8') in my global site config.inc.php, doesn't work in my classes : it reverse back to ISO-8859-1.
Adding the call to the constructor of my top site class resolve this.

Especially when writing PHP scripts for use on different servers, it is a very good idea to explicitly set the internal encoding somewhere on top of every document served, e.g.
mb_internal_encoding("UTF-8");
This, in combination with mysql-statement "SET NAMES 'utf8'", will save a lot of debugging trouble.
Also, use the multi-byte string functions instead of the ones you may be used to, e.g. mb_strlen() instead of strlen(), etc.

To previous example, the PHP notes don't appear to support umlauted characters so there are question marks (?) there instead of what should be umlauated oue. Just substitute any high-order/accented character to see the effect.
