使用 PHP 转换 Microsoft Word 特殊字符

2021-12-31 00:00:00 utf-8 ms-word character-encoding php

我正在尝试转换用户粘贴的包含 MS Word 省略号和长破折号的 Word 文本，然后再进一步处理.

I am trying to convert Word text pasted by users that contain MS Word ellipsis and long dash before processing it further.

我在这里找到了一个旧的建议解决方案http://www.codingforums.com/archive/index.php/t-47163.html ，但它对我不起作用.例如，替换省略号后，变量返回为空.以前从未见过这样的事情:

I found an old proposed solution here to the problem http://www.codingforums.com/archive/index.php/t-47163.html , but it does not work for me. After replacing the ellipsis for example , the variable comes back as empty. Never seen anything like this before:

$src = "Long word dash – and weird Word ellipsis…";
$src = str_replace("‘", "'", $src);
$src = str_replace("’", "'", $src);
$src = str_replace(""", '"', $src);
$src = str_replace(""", '"', $src);
$src = str_replace("–", "-", $src);
$src = str_replace("…", "...", $src);
print $src;

有什么想法吗?

推荐答案

对于在 PHP 中遇到菱形问号的人来说，这种替换 UTF-8 字符的方法比使用 chr 函数效果更好.

For anyone getting the diamond question mark in PHP, this method of replacing UTF-8 characters worked better than using the chr function.

$search = [                 // www.fileformat.info/info/unicode/<NUM>/ <NUM> = 2018
                "xC2xAB",     // « (U+00AB) in UTF-8
                "xC2xBB",     // » (U+00BB) in UTF-8
                "xE2x80x98", // ‘ (U+2018) in UTF-8
                "xE2x80x99", // ’ (U+2019) in UTF-8
                "xE2x80x9A", // ‚ (U+201A) in UTF-8
                "xE2x80x9B", // ‛ (U+201B) in UTF-8
                "xE2x80x9C", // " (U+201C) in UTF-8
                "xE2x80x9D", // " (U+201D) in UTF-8
                "xE2x80x9E", // „ (U+201E) in UTF-8
                "xE2x80x9F", // ‟ (U+201F) in UTF-8
                "xE2x80xB9", // ‹ (U+2039) in UTF-8
                "xE2x80xBA", // › (U+203A) in UTF-8
                "xE2x80x93", // – (U+2013) in UTF-8
                "xE2x80x94", // — (U+2014) in UTF-8
                "xE2x80xA6"  // … (U+2026) in UTF-8
    ];

    $replacements = [
                "<<", 
                ">>",
                "'",
                "'",
                "'",
                "'",
                '"',
                '"',
                '"',
                '"',
                "<",
                ">",
                "-",
                "-",
                "..."
    ];

    str_replace($search, $replacements, $string);
