Question

我正在使用MacRoman char编码保存的CakePHP网站。我想将所有文件更改为UTF-8以进行国际化。对于网站中的所有其他文件，这工作正常。但是，在core.php文件中有一个安全盐，它是一个带有特殊字符的字符串（“！：* etc.）。当我将这个文件保存为UTF-8时，盐被破坏。我可以用git，但这是一个烦恼。

有谁知道如何将字符串从MacRoman转换为UTF-8？

Answer 1

您没有提供足够的信息来确认这一点，但我想盐是以二进制形式使用的。在这种情况下，如果更改了这个二进制流，更改文件的编码将损坏salt，即使字符被正确转换也是如此。

由于前128个字符在UTF-8和Mac OS Roman中相似，因此您不必担心盐是否仅使用这些字符编写。

让我们说盐在某处：

$salt = "a!c‡Œ";

你可以写一下：

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

您可以将所有内容映射到十六进制表示，因为它可能更容易自动化：

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

请参阅表格here。

以下代码段可以自动执行此转换：

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

感谢您的投入，指出了我正确的方向。解决方案是：

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

Answer 3

对于那些无法访问iconv的人来说，这是PHP中的一个函数： http://sebastienguillon.com/test/jeux-de-caracteres/MacRoman_to_utf8.txt.php 它会将MacRoman文本正确转换为UTF-8，您甚至可以决定如何打破连字。

<?php
function MacRoman_to_utf8($str, $break_ligatures='none')
{
    // $break_ligatures : 'none' | 'fifl' | 'all'
    // 'none' : don't break any MacRoman ligatures, transform them into their utf-8 counterparts
    // '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"));
    }

    if($break_ligatures == 'all')
    {
        $str = strtr($str, array("\xDE"=>"fi", "\xDF"=>"fl", "\xAE"=>"AE", "\xBE"=>"ae", "\xCE"=>"OE", "\xCF"=>"oe"));
    }

    $str = strtr($str, array("\x7F"=>"\x20", "\x80"=>"\xC3\x84", "\x81"=>"\xC3\x85",

Answer 4

您是否尝试过mb-convert-encoding？

认为它会是：

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

Answer 5

好奇，您是否尝试过复制盐，保存为UTF-8然后将盐粘贴到适当位置并再次保存？

字符编码：将文件从MacRoman更改为UTF-8会中断字符串
