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

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.

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 "
