php - XMLReader -- 遇到 utf 字符的问题

Question

我正在解析一个巨大的 xml 文件，并且文件的编码是
< ? xml 版本="1.0" 编码="ISO-8859-1" ?>**粗体

db 编码是 utf8，我在将任何内容保存到 db
$sql='SET NAMES "utf8" COLLATE "utf8_swedish_ci"';之前运行此查询

问题是有时一些非标准字符会出现在 xml 文件中，例如
Lycka™ : roman
我知道商标符号来自 windows-1252 编码。

我正在使用 php。我试过utf8_encode。

这里保存在 db和

这是浏览器中的输出

我希望它转换为utf，就是这样

Answer 1

在保存到 db 之前，您是否尝试过在 utf8 中编码字符串？对于 php，有 utf8_encode() 函数，您使用的语言中可能有类似的函数。

Answer 2

我使用了这段代码并且工作正常

function cp1252_to_utf8($str) 
{

        $cp1252_map = array(
                "\xc2\x80" => "\xe2\x82\xac", /* EURO SIGN */
                "\xc2\x82" => "\xe2\x80\x9a", /* SINGLE LOW-9 QUOTATION MARK */
                "\xc2\x83" => "\xc6\x92",     /* LATIN SMALL LETTER F WITH HOOK */
                "\xc2\x84" => "\xe2\x80\x9e", /* DOUBLE LOW-9 QUOTATION MARK */
                "\xc2\x85" => "\xe2\x80\xa6", /* HORIZONTAL ELLIPSIS */
                "\xc2\x86" => "\xe2\x80\xa0", /* DAGGER */
                "\xc2\x87" => "\xe2\x80\xa1", /* DOUBLE DAGGER */
                "\xc2\x88" => "\xcb\x86",     /* MODIFIER LETTER CIRCUMFLEX ACCENT */
                "\xc2\x89" => "\xe2\x80\xb0", /* PER MILLE SIGN */
                "\xc2\x8a" => "\xc5\xa0",     /* LATIN CAPITAL LETTER S WITH CARON */
                "\xc2\x8b" => "\xe2\x80\xb9", /* SINGLE LEFT-POINTING ANGLE QUOTATION */
                "\xc2\x8c" => "\xc5\x92",     /* LATIN CAPITAL LIGATURE OE */
                "\xc2\x8e" => "\xc5\xbd",     /* LATIN CAPITAL LETTER Z WITH CARON */
                "\xc2\x91" => "\xe2\x80\x98", /* LEFT SINGLE QUOTATION MARK */
                "\xc2\x92" => "\xe2\x80\x99", /* RIGHT SINGLE QUOTATION MARK */
                "\xc2\x93" => "\xe2\x80\x9c", /* LEFT DOUBLE QUOTATION MARK */
                "\xc2\x94" => "\xe2\x80\x9d", /* RIGHT DOUBLE QUOTATION MARK */
                "\xc2\x95" => "\xe2\x80\xa2", /* BULLET */
                "\xc2\x96" => "\xe2\x80\x93", /* EN DASH */
                "\xc2\x97" => "\xe2\x80\x94", /* EM DASH */

                "\xc2\x98" => "\xcb\x9c",     /* SMALL TILDE */
                "\xc2\x99" => "\xe2\x84\xa2", /* TRADE MARK SIGN */
                "\xc2\x9a" => "\xc5\xa1",     /* LATIN SMALL LETTER S WITH CARON */
                "\xc2\x9b" => "\xe2\x80\xba", /* SINGLE RIGHT-POINTING ANGLE QUOTATION*/
                "\xc2\x9c" => "\xc5\x93",     /* LATIN SMALL LIGATURE OE */
                "\xc2\x9e" => "\xc5\xbe",     /* LATIN SMALL LETTER Z WITH CARON */
                "\xc2\x9f" => "\xc5\xb8"      /* LATIN CAPITAL LETTER Y WITH DIAERESIS*/
        );

        return  strtr(utf8_encode($str), $cp1252_map);
}


$str = cp1252_to_utf8( iconv("UTF-8", "ISO-8859-1//TRANSLIT", $str));
