Char編碼：將文件從MacRoman更改爲UTF-8中斷字符串

我正在CakePHP站點上保存MacRoman char編碼。我想將所有文件更改爲UTF-8進行國際化。對於網站中的所有其他文件，這可以正常工作。但是，在core.php文件中有一個安全鹽，它是一個帶有特殊字符（「！：*」）的字符串。當我把這個文件保存爲UTF-8時，鹽會被損壞。 git的，但它是一個煩惱Char編碼：將文件從MacRoman更改爲UTF-8中斷字符串

有誰知道我可以將字符串從的MacRoman轉換爲UTF-8

你沒有提供足夠的信息來證實這一點，但我猜鹽是以二進制形式使用的。在這種情況下，即使正確轉換了字符，如果更改此二進制流，則更改該文件的編碼將會破壞salt。

由於UTF-8和Mac OS Roman中的前128個字符相似，因此您不必擔心salt是否僅使用這些字符來編寫。

比方說，鹽是地方：

$salt = "a!c‡Œ";

你可以代替寫：

$salt = "a!c\xE0\xCE";

您可以將所有映射到其十六進制表示，因爲它可能會更容易實現自動化：

$salt = "\x61\x21\x63\xE0\xCE";

見表here。

下面的代碼片段可以自動完成這一轉換：

$res = ""; 
foreach (str_split($salt) as $c) { 
    $res .= "\\x".dechex(ord($c)); 
} 
echo $res;

這幫助我走到了一個很長的兔子洞的盡頭。非常感謝。隨着你的片段，我能夠真正看到我的角色發生了什麼，並深入瞭解我的編碼問題。 – 2014-06-15 03:49:55

你試過mb-convert-encoding

認爲這將是：？？

$str = mb_convert_encoding($str, "macintosh", "UTF-8");

只是好奇，你有沒有嘗試複製鹽，保存爲UTF-8，然後將鹽粘貼到原位並再次儲存？

是的，我應該提到我曾嘗試過，但沒有幫助 – igniteflow 2010-07-09 09:50:39

感謝您的輸入，指出我在正確的方向。解決的辦法是：

$salt = iconv('UTF-8', 'macintosh', $string);

對於那些沒有進入到這裏的iconv是誰在PHP函數： http://sebastienguillon.com/test/jeux-de-caracteres/MacRoman_to_utf8.txt.php 將正確的MacRoman文本轉換爲UTF-8，你甚至可以決定要如何突破連字。

<?php

    // 'fifl' : break only fi ("\xDE" => "fi") and fl ("\xDF"=>"fl") 
    // 'all' : break fi, fl and also AE ("\xAE"=>"AE"), ae ("\xBE"=>"ae"), OE ("\xCE"=>"OE") and oe ("\xCF"=>"oe") 

    if($break_ligatures == 'fifl') 
    { 
     $str = strtr($str, array("\xDE"=>"fi", "\xDF"=>"fl"));
