Convert latin1 characters on a UTF8 table into UTF8

Only today I realized that I was missing this in my PHP scripts:

mysql_set_charset('utf8');

All my tables are InnoDB, collation "utf8_unicode_ci", and all my VARCHAR columns are "utf8_unicode_ci" as well. I have mb_internal_encoding('UTF-8'); on my PHP scripts, and all my PHP files are encoded as UTF-8.

So, until now, every time I "INSERT" something with diacritics, example:

mysql_query('INSERT INTO `table` SET `name`="Jáuò Iñe"');

The 'name' contents would be, in this case: Jáuò Iñe.

Since I fixed the charset between PHP and MySQL, new INSERTs are now storing correctly. However, I want to fix all the older rows that are "messed" at the moment. I tried many things already, but it always breaks the strings on the first "illegal" character. Here is my current code:

$m = mysql_real_escape_string('¿<?php echo "¬<b>\'PHP &aacute; (á)ţăriîş</b>"; ?> ă-ţi abcdd;//;ñç´พดแทฝใจคçăâξβψδπλξξςαยนñ ;');mysql_set_charset('utf8');mysql_query('INSERT INTO `table` SET `name`="'.$m.'"');mysql_set_charset('latin1');mysql_query('INSERT INTO `table` SET `name`="'.$m.'"');mysql_set_charset('utf8');$result = mysql_iquery('SELECT * FROM `table`');while ($row = mysql_fetch_assoc($result)) {    $message = $row['name'];    $message = mb_convert_encoding($message, 'ISO-8859-15', 'UTF-8');    //$message = iconv("UTF-8", "ISO-8859-1//IGNORE", $message);    mysql_iquery('UPDATE `table` SET `name`="'.mysql_real_escape_string($message).'" WHERE `a1`="'.$row['a1'].'"');}

It "UPDATE"s with the expected characters, except that the string gets truncated after the character "ă". I mean, that character and following chars are not included on the string.

Also, testing with the "iconv()" (that is commented on the code) does the same, even with //IGNORE and //TRANSLIT

I also tested several charsets, between ISO-8859-1 and ISO-8859-15.
