用戶友好的網址從功能

我有一些困難時，處理一個只生成英文字符的網址，我需要使它適合葡萄牙，處理特殊字符的拉丁國家。用戶友好的網址從功能

創建鏈接的功能是：

function generateSafeUrls($url = '') { 
    ## normalize accented characters 
    $url = strtr($url, "\xA1\xAA\xBA\xBF\xC0\xC1\xC2\xC3\xC5\xC7\xC8\xC9\xCA\xCB\xCC\xCD\xCE\xCF\xD0\xD1\xD2\xD3\xD4\xD5\xD8\xD9\xDA\xDB\xDD\xE0\xE1\xE2\xE3\xE5\xE7\xE8\xE9\xEA\xEB\xEC\xED\xEE\xEF\xF0\xF1\xF2\xF3\xF4\xF5\xF8\xF9\xFA\xFB\xFD\xFF\ã", "_ao_AAAAACEEEEIIIIDNOOOOOUUUYaaaaaceeeeiiiidnooooouuuyy"); 
    ## further character processing 
    $url = strtr($url, array("\xC4"=>"Ae", "\xC6"=>"AE", "\xD6"=>"Oe", "\xDC"=>"Ue", "\xDE"=>"TH", "\xDF"=>"ss", "\xE4"=>"ae", "\xE6"=>"ae", "\xF6"=>"oe", "\xFC"=>"ue", "\xFE"=>"th", "\ã"=>"a")); 
    ## make sure its only english and dashes 
    $search = array("/[^a-zA-Z0-9\/]/", "/--+/"); 
    $replace = array("-", "-"); 
    $url = preg_replace($search, $replace, $url); 
    ## return safe url 
    return($url); 
}

我可以看到函數替換的空間以「 - 」，這將是偉大，是因爲如果該函數替換爲「C」的「C」 ，「あ」等。事情是，我不知道如何做到這一點。

我不想讓你工作，因爲我總是說，給我的技巧和提示，我將這麼多的讚賞;）

親切問候大家！謝謝！

這裏是我的：
