When building websites, developers often encounter the need to display certain characters that aren’t available on a standard keyboard. This is where HTML entities come into play. In this article, we will explore the concept of HTML entities for Unicode characters, how to use them, and best practices to follow.
I. Introduction
A. Definition of HTML Entities
HTML entities are special codes that represent characters in HTML. They allow web developers to render characters that might otherwise be misinterpreted by the browser or that may not be available on the keyboard. Entities are often represented with an ampersand (&) followed by a code and ending with a semicolon (;).
B. Importance of Unicode in Web Development
Unicode is a character encoding standard that allows for the representation of text in any writing system. This is crucial for web development, as it ensures that text is rendered correctly across different browsers, devices, and languages. Using HTML entities that correspond to Unicode characters allows developers to maintain this consistency.
