This practice is often enabled through reverse engineering web fonts by intercepting font files through developer tools or decoding base64 strings. In some cases, it may also help extract hidden text from websites that use font-based obfuscation to prevent scraping. This blog explores how proprietary fonts can be reverse-engineere...
