Twemoji is a library designed to provide consistent emoji rendering across different web browsers and operating systems. It functions by identifying and extracting Unicode emoji sequences from text and replacing them with standardized graphical assets, ensuring that symbols appear identical regardless of the underlying platform.
The project distinguishes itself by offering a comprehensive toolkit that combines parsing logic with a library of scalable vector and rasterized image assets. This allows for the programmatic transformation of text into high-quality visual representations, supporting both crisp vector scaling and lightweight rasterized display requirements.
The library includes utilities for character encoding conversion and codepoint mapping, which facilitate the accurate handling of complex symbols within document object models. It also provides filtering capabilities that allow developers to apply custom logic to determine which characters are converted into images and which remain as standard text.
