搜索字符串中特殊字符并替换它们的最有效方法是什么？

Question

我试图搜索字符串中的所有特殊字符并将其转义。输入字符串必须是故障安全的，所以我需要转义字符。 示例String查找示例如下："Foo Bar "Gone Wild "- <br>Ted Talk</br> " 为了确保String看起来仍然相同，之后需要"Foo Bar \"Gone Wild \" \- \<br\>Ted Talk \<\/br\>"

我提出了这个解决方案：

 final String[] metaCharacters = {"\\", "^", "$", "{", "}", "[", "]", "(", ")", ".", "*", "+", "?", "|", "<", ">", "-", "&", "#"};
    String outputString = "";
    for (int characterIndex = 0; characterIndex < metaCharacters.length; characterIndex++) {
        if (inputString.contains(metaCharacters[characterIndex])) {
            outputString = inputString.replace(metaCharacters[characterIndex], "\\" + metaCharacters[characterIndex]);
        }
    }

但我对此并不满意。它用Java编写。
