What is the Unicode character table?
The Unicode character table is a visual representation of all characters assigned in the Unicode standard. This table covers a wide range of languages ​​and symbols, allowing for the representation of various writing systems and special characters in a single data set. Each Unicode character is identified by a unique hexadecimal number , known as a code point.

Using Unicode characters in CSS.
In CSS, we can use Unicode characters to add interesting visual elements to our web designs. There are several ways to apply Unicode characters in CSS:

a) Using escape sequences: Escape sequences allow us to represent Unicode characters by their code point. For example, the character «√» is represented by the sequence «\221A». We can use this sequence in properties such as content, to add custom icons or symbols to our elements.

b) Using the character name: CSS also allows us to use the Unicode character name directly. For example, instead of using “\221A”, we can write “√” to represent the square root character. This can make our code more readable and maintainable.

c) Using Custom Fonts: Another way to apply Unicode characters in CSS is through custom fonts. We can use fonts that contain specific Unicode characters and then apply those fonts to specific elements on our website. This gives us the flexibility to use Unicode characters anywhere in our design, from headings to paragraph text.
