Comment résoudre l'erreur « L'encodage des caractères du document HTML n'a pas été déclaré » ?

Resolving the HTML Character Encoding Error

When submitting a form, users often encounter the error message, "The character encoding of the HTML document was not declared." This error can lead to garbled text in certain browser configurations due to the presence of non-US-ASCII characters.

To address this issue, it is crucial to declare the character encoding explicitly. In the provided HTML code (insert.html), ensure that the section includes the following meta tags:

<meta content="text/html;charset=utf-8" http-equiv="Content-Type">
<meta content="utf-8" http-equiv="encoding">

These meta tags specify that the page uses the UTF-8 character encoding. UTF-8 is a widely accepted Unicode-based encoding that supports a wide range of languages and characters.

Cautions:

1. Place these meta tags directly after the tag to ensure they are not overridden by other content.
2. Avoid any content, even comments, appearing between the tag and the meta tags, as this can disrupt the correct encoding declaration.
