Emojis have become vital in digital communication, allowing users to express emotions succinctly, especially within character-limited platforms like Twitter. However, compatibility issues arise when different devices and browsers render emojis differently, often resulting in confusion or miscommunication when they appear as empty boxes or unintended characters. This inconsistency is due to varying software support across platforms, each interpreting emoji Unicode in its unique way. To address this, Google developed the EmojiCompat library, which ensures emojis display correctly across older Android versions by updating emoji fonts dynamically. Despite this advancement, developers must implement the library individually into their applications, as it is not a native Android function. Ensuring emoji compatibility requires thorough testing across multiple browsers and operating systems, a process facilitated by tools like LambdaTest.
