There are multiple benefits to using HTML symbols, also called character entities. Such as:

• Firstly, they are compatible with all types of web browsers and operating systems, ensuring consistent display across various devices.
• Secondly, these symbols can enhance accessibility for people who rely on assistive technologies, such as visually impaired users who can better comprehend content with symbols such as “≠” indicating “not equal to”.
• Thirdly, HTML symbols provide a uniform way to represent special characters and symbols, which ensures that content appears the same on different platforms and fonts.
• Additionally, using HTML symbols can enhance the readability of content by dividing long blocks of text and allowing readers to easily scan for important information.
• Lastly, HTML symbols are user-friendly and save time and effort by eliminating the need to type out full names or codes for special characters or symbols.
