What are these strange characters in the URL

URLs can only be sent over the Internet using the ASCII character set. Because URLs often contain characters outside the ASCII set, the URL must be converted to the correct ASCII format. URL encoding replaces dangerous ASCII characters with% followed by two hexadecimal digits. URLs cannot contain spaces. URL encoding usually replaces the space with a plus sign (+) or% 20. The encoding of URLs and just binary data into a sequence of letters, numbers and some special characters of the Latin alphabet on the Internet was associated with the limitation of physical devices to transmit only alphanumeric characters. In URLs, this encoding is typically used to transfer Unicode characters (typically UTF-8) into a sequence of two bytes written in hexadecimal notation.

The subset of characters that are allowed in the URL is slightly wider than alphanumeric characters, so you can use hyphen and underscore in the URL, but you cannot, for example, use single or double quotes. Some characters are used to separate parameters in the URL, and their encoding in this case will be unauthorized. If the URL contains non-ASCII characters, the URL is converted. Cyrillic letters, letters with diacritics, ligatures, hieroglyphs should be recoded. URL encoding converts this address to ASCII format. The URL encoder replaces unsafe ASCII characters with a (%) sign followed by two hexadecimal numbers that match the character values in the ISO-8859-1 encoding.
