How to encode emojis in WordPress using wp_encode_emoji

The wp_encode_emoji() function in WordPress is a part of the Emoji functionality. This function is designed to convert all the emoji in a text into their HTML entity, which can be useful in ensuring the correct display of these characters across different browsers and devices.

One of the main purposes of the wp_encode_emoji() function is to aid in the compatibility of emojis. Not all systems and browsers are equipped to handle the wide variety of emojis available today. By converting emojis into their HTML entities, it can help to ensure that the emoji is displayed as intended, regardless of the user’s system or browser.

It is worth noting that the wp_encode_emoji() function does not affect the original text. Instead, it returns a new string with the emojis converted into their HTML entities. This allows the original text to remain intact while still providing a version that is more likely to be correctly displayed across different systems and browsers.

The wp_encode_emoji() function is a part of WordPress’s efforts to provide comprehensive emoji support and ensure the correct display of these characters in a variety of contexts.
