If one of your sql dump was poorly encoded and you want to convert a mysql column from iso to utf-8, here is a small conversion table for common characters :

UPDATE `table_name` SET `column_name` = REPLACE(`column_name`,'’','‘');
UPDATE `table_name` SET `column_name` = REPLACE(`column_name`,'°','°');
UPDATE `table_name` SET `column_name` = REPLACE(`column_name`,'à','Ã ');
UPDATE `table_name` SET `column_name` = REPLACE(`column_name`,'á','á');
UPDATE `table_name` SET `column_name` = REPLACE(`column_name`,'â','â');
UPDATE `table_name` SET `column_name` = REPLACE(`column_name`,'ã','ã');
UPDATE `table_name` SET `column_name` = REPLACE(`column_name`,'ä','ä');
UPDATE `table_name` SET `column_name` = REPLACE(`column_name`,'å','Ã¥');
UPDATE `table_name` SET `column_name` = REPLACE(`column_name`,'æ','æ');
UPDATE `table_name` SET `column_name` = REPLACE(`column_name`,'ç','ç');
UPDATE `table_name` SET `column_name` = REPLACE(`column_name`,'è','è');
UPDATE `table_name` SET `column_name` = REPLACE(`column_name`,'é','é');
UPDATE `table_name` SET `column_name` = REPLACE(`column_name`,'ê','ê');

UPDATE `table_name` SET `column_name` = REPLACE(`column_name`,'í','Ã' );
UPDATE `table_name` SET `column_name` = REPLACE(`column_name`,'î','î');
UPDATE `table_name` SET `column_name` = REPLACE(`column_name`,'ï','ï');

If you have tried repeatedly to produce an excel export of data from a database in UTF-8 with PHP, you probably came to some surprising results.

Our dear friend Microsoft uses in fact the encoding UTF-16le.

Thus, to form a excel document (here a list of users), "simply" do:

header("Content-Type: application/; charset=UTF-16LE");
header("Content-Disposition: attachment; filename=\"Export Excel\"");
$sql = "SELECT * FROM users ORDER BY user_name";
$req = mysql_query($sql);
while ($row = @mysql_fetch_assoc($req))
      <td><?=substr(chr(255).chr(254).mb_convert_encoding($row['user_sname'], "UTF-16LE", "UTF-8"),2)?></td>
      <td><?=substr(chr(255).chr(254).mb_convert_encoding($row['user_fname'], "UTF-16LE", "UTF-8"),2)?></td>
      <td><?=substr(chr(255).chr(254).mb_convert_encoding($row['user_email'], "UTF-16LE", "UTF-8"),2)?></td>
