with "filter", you mean remove them?

You could place all the letters you wanna remove in an array and then use str_ireplace() (if you use PHP 5) to delete them.
ex:

[color=blue]<?php
$string = 'bla bla bla ëíñçíàéö bla bla ñç...';

$chars = array('ë', 'í', 'ñ', 'ç', 'í', 'à', 'é', 'ö');
echo str_ireplace($chars, '', $string);
?>[/color]

Why are you filtering these? You can remove non-ASCII characters via:

[code]
<pre>
<?php
$string = 'to filter symbols like ëíñçíàéö etc.';
echo preg_replace('/[^\x0-\x7f]/', '', $string);
?>
</pre>
[/code]

no i mean replace them with like this:

ë=>e
í=>i
ñ=>n
ç=c
í=>i
à=>a
é=>e
ö=>o

[code=php:0]<?php

$string = 'bla bla bla ëíñçíàéö bla bla ñç...';

$change = array('ë', 'í', 'ñ', 'ç', 'í', 'à', 'é', 'ö');
$tothis = array('a', 'i', 'n', 'c', 'i', 'a', 'e', 'o');

echo str_replace($change, $tothis, $string);

?>[/code]

Have a look at [url=http://www.phpfreaks.com/forums/index.php/topic,100331.msg395933.html#msg395933]this[/url] post.

It does not work if $change contains non-ASCII chars like α - β - Ğ - ğ - İ - ı - Ş - ş


<?php

$string = 'bla bla bla ëíñçíàéö bla bla ñç...';

$change = array("α",  "β",  "Ğ", "ğ" );

$tothis = array('a', 'i', 'n', 'c', 'i', 'a', 'e', 'o');

echo str_replace($change, $tothis, $string);

?>

I ran across [url=http://us2.php.net/manual/en/function.mb-convert-encoding.php#69412]this[/url]; "some code to convert latin diacritics to their traditional 7bit representation."
