Percent Encoding

This Typst library offers function for encoding and decoding percent escape sequences.
These are typically used to encode unsafe or non-ASCII characters in URLs.
Supported by this library is only Typst's native character encoding and defacto web standard: UTF-8.

Read the manual for further information.

Usage

You can directly import the package from Typst universe:

#import "@preview/percencode:0.1.0": *

Example

Sanitize URLs

The method url-encode can be used to escape unsafe characters (as in RFC 2396) in URL strings.

Example:

https://example.com/how much is 23€ wörth?

Results in:

https://example.com/how%20much%20is%2023%E2%82%AC%20w%C3%B6rth?

Encoding

Encode an entire string:

#percent-encode("Hello, World!")

Results in:

%48%65%6C%6C%6F%2C%20%57%6F%72%6C%64%21

Decoding

Decode an entire string:

#percent-decode("%48%65%6C%6C%6F%2C%20%57%6F%72%6C%64%21")

Results in:

Hello, World!
