编码问题...windows-1255到utf 8？

Question

从windows-1255到utf-8的编码转换在我知道之前就被问过了，但我仍然得到了不同的结果，我无法解决它。

第一个问题是“php iconv()或mb_convert_encoding()是否支持windows-1255？”在测试时，它返回几个输出(使用//ignore & //translate)，但它根本不能很好地工作。

我正在查看mb_list_encodings()输出，它不包括window-1255...使用windows-1255输入(从网上抓取)播放和测试mb_detect_encoding()不会返回正确的字符集...

您应该能够使用带有要转换的字符的关联数组的strtr (数据为available from MSDN，并在下面将其转换为PHP数组)。请注意，在此代码中，保留字节值被替换为U+FFFD替换字符("\xef\xbf\xbd")。

function win1255ToUtf8($str) {
    static $tbl = null;
    if (!$tbl) {
        $tbl = array_combine(range("\x80", "\xff"), array(
            "\xe2\x82\xac", "\xef\xbf\xbd", "\xe2\x80\x9a", "\xc6\x92",
            "\xe2\x80\x9e", "\xe2\x80\xa6", "\xe2\x80\xa0", "\xe2\x80\xa1",
            "\xcb\x86", "\xe2\x80\xb0", "\xef\xbf\xbd", "\xe2\x80\xb9",
            "\xef\xbf\xbd", "\xef\xbf\xbd", "\xef\xbf\xbd", "\xef\xbf\xbd",
            "\xef\xbf\xbd", "\xe2\x80\x98", "\xe2\x80\x99", "\xe2\x80\x9c",
            "\xe2\x80\x9d", "\xe2\x80\xa2", "\xe2\x80\x93", "\xe2\x80\x94",
            "\xcb\x9c", "\xe2\x84\xa2", "\xef\xbf\xbd", "\xe2\x80\xba",
            "\xef\xbf\xbd", "\xef\xbf\xbd", "\xef\xbf\xbd", "\xef\xbf\xbd",
            "\xc2\xa0", "\xc2\xa1", "\xc2\xa2", "\xc2\xa3", "\xe2\x82\xaa",
            "\xc2\xa5", "\xc2\xa6", "\xc2\xa7", "\xc2\xa8", "\xc2\xa9",
            "\xc3\x97", "\xc2\xab", "\xc2\xac", "\xc2\xad", "\xc2\xae",
            "\xc2\xaf", "\xc2\xb0", "\xc2\xb1", "\xc2\xb2", "\xc2\xb3",
            "\xc2\xb4", "\xc2\xb5", "\xc2\xb6", "\xc2\xb7", "\xc2\xb8",
            "\xc2\xb9", "\xc3\xb7", "\xc2\xbb", "\xc2\xbc", "\xc2\xbd",
            "\xc2\xbe", "\xc2\xbf", "\xd6\xb0", "\xd6\xb1", "\xd6\xb2",
            "\xd6\xb3", "\xd6\xb4", "\xd6\xb5", "\xd6\xb6", "\xd6\xb7",
            "\xd6\xb8", "\xd6\xb9", "\xef\xbf\xbd", "\xd6\xbb", "\xd6\xbc",
            "\xd6\xbd", "\xd6\xbe", "\xd6\xbf", "\xd7\x80", "\xd7\x81",
            "\xd7\x82", "\xd7\x83", "\xd7\xb0", "\xd7\xb1", "\xd7\xb2",
            "\xd7\xb3", "\xd7\xb4", "\xef\xbf\xbd", "\xef\xbf\xbd",
            "\xef\xbf\xbd", "\xef\xbf\xbd", "\xef\xbf\xbd", "\xef\xbf\xbd",
            "\xef\xbf\xbd", "\xd7\x90", "\xd7\x91", "\xd7\x92", "\xd7\x93",
            "\xd7\x94", "\xd7\x95", "\xd7\x96", "\xd7\x97", "\xd7\x98",
            "\xd7\x99", "\xd7\x9a", "\xd7\x9b", "\xd7\x9c", "\xd7\x9d",
            "\xd7\x9e", "\xd7\x9f", "\xd7\xa0", "\xd7\xa1", "\xd7\xa2",
            "\xd7\xa3", "\xd7\xa4", "\xd7\xa5", "\xd7\xa6", "\xd7\xa7",
            "\xd7\xa8", "\xd7\xa9", "\xd7\xaa", "\xef\xbf\xbd", "\xef\xbf\xbd",
            "\xe2\x80\x8e", "\xe2\x80\x8f", "\xef\xbf\xbd",
        ));
    }
    return strtr($str, $tbl);
}

我用这个PHP脚本生成了上面的代码：

function win1255ToUtf8($str) {
    static $tbl = null;
    if (!$tbl) {
        $tbl = array_combine(range("\x80", "\xff"), array(
            <?php

        function encodeString($str) {
            return '"' . preg_replace('/../', '\x$0', bin2hex($str)) . '"';
        }

        function codepointToUtf8($n) {
            return mb_convert_encoding(pack('V', $n), 'UTF-8', 'UTF-32LE');
        }

        $text = strip_tags( file_get_contents( 'http://msdn.microsoft.com/en-us/goglobal/cc305148.aspx') );
        preg_match_all('/([0-9A-F]{2}) = U\+([0-9A-F]{4})/', $text, $matches, PREG_SET_ORDER);

        $table = array_fill(0, 128, "\xef\xbf\xbd");
        foreach ($matches as $match) {
            $input = hexdec($match[1]) - 128;
            if ($input >= 0) {
                $table[$input] = codepointToUtf8(hexdec($match[2]));
            }
        }

        $buf = '';
        foreach ($table as $from => $to) {
            $buf .= encodeString($to) . ', ';
        }
        echo wordwrap(substr($buf, 0, -1), 68, "\n            "), "\n";

?>
        ));
    }
    return strtr($str, $tbl);
}

找到了这个，它对我很有效

$content = iconv("CP1255", "UTF-8", $content);
