How can I Replace Non-English Characters in URLs?

I want to replace;

'Č' => 'c',
'č' => 'c',
'Ğ' => 'g',
'ğ' => 'g',
'Ş' => 's',
'ş' => 's',
'İ' => 'i',
'ı' => 'i',
'?' => 'c',
'?' => 'c',
'?' => 'u',
'?' => 'u',
'?' => 'o',
'?' => 'o',
'ı' => 'i',
'İ' => 'i',
'?' => 'i',
'?' => 'a',
'?' => 'e',
'?' => 'a',
'?' => 'e');

How can I do that, any idea? Also German sites should have same problem
