URI Encoder/Decoder

URL encoding, is also known as URI encoding or Percent encoding. It converts characters into a format, that only contains ASCII characters compatible with the HTTP protocol.

URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits, or Unicode characters with % followed by multiple pairs of hexadecimal digits.

Common ASCII characters that are also encoded are:

• Space is encoded either as + sign or %20
• + sign is encoded as %2B
• / is encoded as %2F
• ? is encoded as %3F

Other reserved characters listed by RFC 3986: `!` `#` `$` `&` `'` `(` `)` `*` `,` `:` `;` `=` `@` `[` `]`
