How to do URL encoding of value which is already in %
问题
用户输入: ABC!123%C56
期望输出: ! 和 % 符号应该被编码，但是 ! 符号被编码了，而 % 符号没有被编码，因为 %C 已经是其他某个符号的值。请提供解决方案，如何对 % 符号进行编码。
英文翻译

你可以匹配用户输入的符号中是否包含%。如果它包含%，你可以将%替换为一个特殊符号（通常用户不会输入的符号）。尽量避免选择用户常用的符号。例如，<p>代表百分号。我认为<p>符号很少使用。如果需要解码它，将<p>替换为%。
> 例如：ABC!123%C56 --> ABC!123<p>C56
英文翻译
You can match whether% is contained in the symbol entered by the user. If it contains % , you can replace% with a special symbol (the symbol that the user does not normally enter). Try to avoid selecting the symbols that users will use. For example, <p> stands for percent. I think the <p> symbol is rarely used. If you need to decode it, replace <p> with % .
> for example: ABC!123%C56 --> ABC!123<p>C56
