Explanation:
- The above code uses functions to class the respective class. Before that, we have declared metadata for the encoding process. Here we have assigned an element with another language. Unfortunately, ASCII doesn’t have compatibility to access. Therefore, we have declared UTF-8 to support the type.
Output:
Conclusion
So that’s all about the encoding of UTF-8 in HTML. We have gone through Unicode and encodes in the HTML briefly and the implementation of HTML and JavaScript. In this emerging software world, the character sets are not made so feasible; therefore, there comes character encoding schemes to be done with the HTML and other programming languages. Therefore, it is said that it is best to use UTF-8 everywhere where it doesn’t need any conversions encoding.
