Reserved and unsafe characters in URLs

Reserved and unsafe characters in URLs

If you need to use a character in a URL that does not belong to this character set, you will encode the character with a special symbol.

For example: the most commonly used spaces are indicated by%20, e.g. http://www.google.com/new%20171130.html

In addition to those characters that cannot be displayed, you need to encode those reserved (reserved) characters and unsafe (unsafe) characters in the URL.

The so-called reserved characters are those characters that have a particular meaning in the URL. Unsafe characters are characters that have no special meaning in the URL, but may have special meaning in the context in which the URL is located. For example, double quotation marks ("")

In general, if you have questions about whether a character can be used in a URL, you should always use the encoding of that character. All characters except letters, numbers, and characters $-_.+!* ' () should be encoded;
