Overview

The UnicodeEmojiExtractor processes HTML files containing emoji data from the Unicode consortium. It extracts emoji images and their skin tones variations from base64-encoded images in the HTML files and saves them to the appropriate directories in the project’s emoji system.

The extractor handles two types of files:

  1. emoji-list.html - Contains base emoji images

  2. emoji-modifier-sequences.html - Contains emoji variations (e.g., skin tones)
