wrong letters in email

[greyow]

Description:
I use hungarian language. There are two characters which not encode the utf8_encode function. utf8_encode translate only ISO-8859-1 characters, so I have ? characters in email.

classes/ps_main.php:583: $mail->Body = vmAbstractLanguage::safe_utf8_encode( $mail->Body, $mail->CharSet );
-> classes/language.class.php 153:  $text = utf8_encode(utf8_decode($text));

Steps to replicate:
<?php
$test_s = "öő";
$deco_s = utf8_decode($test_s);
$enco_s = utf8_encode($deco_s);
echo "start: $test_s decode: $deco_s encode: $enco_s \n";
?>

result:
start: öő decode: �? encode: ö?


Proposed fix(es):
Don't use utf8_[de/en]code please.
