URL Encoder-Decoder
A URL encoder is a utility that transforms text strings into a format suitable for use within web addresses. It achieves this by replacing unsafe characters, such as spaces and symbols, with their percent-encoded equivalents.

What is URL encoding?
URL Encoding (also known as percent-encoding) is a method to encode arbitrary data in a uniform resource identifier (URI) using only the ASCII characters legal within a URI.
URLs are designed to use characters from the ASCII character set. Because URLs often need to include characters outside this set (like spaces or non-ASCII characters), or characters with special meaning within the URL syntax, URL encoding is necessary.
Reserved Characters
RFC 3986 defines "reserved characters" as those that have special meaning within the URL syntax. These characters must be encoded when they appear as data within a URL component, to prevent them from being misinterpreted as URL syntax.

How URL-Encoding works?
ASCII Characters:
- These characters, as defined by RFC 3986, have special meaning within the URL structure.
- When they need to be treated as data (not as URL syntax), they are converted to their corresponding ASCII hexadecimal representation.
- The two hexadecimal digits of the ASCII value are then prefixed with a percent sign (%).
Non-ASCII Characters:
- These characters fall outside the standard ASCII range.
- They are first encoded into their UTF-8 byte representation.
- Each byte of the UTF-8 representation is then converted into its hexadecimal equivalent.
- Each hexadecimal byte is prefixed with a percent sign (%).
