What is URL Encoding?
URL Encoding (Percent encoding) is the process of replacing unallowed characters in a URL string with a safe combination of characters (For example, space becomes %20, "&" becomes %26...).
When to use URL Encoder?
Internet URL strings only accept standard US-ASCII characters. When you design an API that attaches parameters with special characters, for example GET parameter ?search=hà nội, the system will immediately throw a network error. For it to run smoothly on the Server, the URL must be Encoded to ?search=h%C3%A0%20n%E1%BB%99i.
