Declaring Character Encoding to Resolve Garbled Text Issue

When encountering the "Character encoding of the HTML document was not declared" error, it is crucial to specify the character encoding within the HTML document itself. This ensures that characters outside the US-ASCII range render correctly in browsers.

The error you are experiencing stems from the lack of character encoding declaration in your HTML document, "insert.html." To resolve this issue, add the following meta tags as the first lines within the section:

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

Copy after login

These meta tags inform browsers of the character encoding used throughout the HTML document. It is important to place these meta tags immediately after the tag, as anything preceding them (including comments) can interfere with their proper function.

After making these changes, your "insert.html" document should appear as below:

<!DOCTYPE html PUBLIC"-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <meta content="text/html;charset=utf-8" http-equiv="Content-Type">
        <meta content="utf-8" http-equiv="encoding">
        <title>insert page</title>
    </head>
    <body>
        <h1> Insert Page </h1>
        <form action="insert.php" method="post"  enctype="application/x-www-form-urlencoded" >

Copy after login
