And if you don't want to worry about so many different charset codings or if htmlentities doesn't work for you, here the alternative: I used mysqli DB connection (and PHPV5) Form post for writing/inserting to MySQl DB.

$Notes = $_POST['Notes']; //can be text input or textarea.

$charset = mysqli_character_set_name($link);  //mysqli connection
printf ("To check your character set but not necessary %s\n",$charset);  

$Notes = str_replace('"', '"', $Notes);  //double quotes for mailto: emails.  
$von = array("ä","ö","ü","ß","Ä","Ö","Ü"," ","é");  //to correct double whitepaces as well
$zu  = array("ä","ö","ü","ß","Ä","Ö","Ü"," ","é");  
$Notes = str_replace($von, $zu, $Notes);  
echo " Notes:".$Notes."
" ;  
$Notes = mysqli_real_escape_string($link, $Notes); //for mysqli DB connection.
// Escapes special characters in a string for use in an SQL statement

echo " Notes:".$Notes ;  //ready for inserting
