如何替换不可打印的 unicode 字符 (Javascript) [英] How to replace non-printable unicode characters (Javascript)

问题描述

我已经浪费了大量时间处理字符串(由其他来源生成)，我发现问题在于字符串具有不可打印的字符.今天我正在处理javascript.有谁知道如何在 javascript 中替换不可打印的 unicode 字符?

I've already wasted a good amount of time dealing with strings (generated by some other source) and I found out that the problem was that the strings have non-printable characters. Today I am dealing with javascript. Does anyone know how to replace non-printable unicode characters in javascript?

我在这里发现了类似的东西:

如何替换不可打印的 Unicode 字符在 Java 中?

my_string.replaceAll("\p{C}", "?");

这里:

非ascii 字符添加表单输入仅与Safari 浏览器

filename.replace(/[^a-z0-9.]+/gi, "");

最后一个选项替换所有不在括号中的字符.无论我使用哪种语言，这总是会在我的后端咬我，而且我厌倦了试图找出哪些字符弄乱了我的代码.出于这个原因，我希望能够用可见的东西替换所有那些不可见的字符，以便我以后可以完全删除它们.

The last option replaces all the characters that are not in the brackets. This is something that has always comes to bite me in my rear end no matter what language I'm working on and I'm tired of trying to figure out what characters are messing up my code. For this reason I want to be able to replace all those invisible characters for something visible so that I can later remove them completely.
