The Unicode Emoji ID is a unique identifier created by the Unicode Consortium for sequencing Unicode Emoji characters. The Unicode Emoji ID may be helpful if you are storing the universe of emojis in a database.

And what is Unicode? From Unicode's official website: "Unicode is the foundation for text in all modern software: it's how all mobile phones, desktops, and other computers represent the text of every language."

A Unicode Code Point is a value in the Unique Code Space (a range of integers from 0 to 10FFFF₁₆). Each unique identifier begins with the letter "U" (for Unicode), followed by a plus sign, and four to six hex (base 16) numbers. If you are developing a database-driven web application, you may want to include this data point.

The HTML Entity Hexadecimal value is the HTML representation of the Unicode Code Point using hexadecimal. It is a created by concatenating the characters "&#x" to the beginning of the Unicode Code Point and concatenating a semicolon to the end of the Unicode Code Point.

The HTML Entity Hexadecimal value is used to add emojis to your websites! You can also store them in your database (without having to change your encoding). You definitely want this data in your database.

The HTML Entity Decimal value is the HTML representation of the Unicode Code Point using decimal. Using the decimal value works similarly to using the HTML Entity Hexadecimal value but there is a conversion process (to convert a hexadecimal value to a decimal value).
