Final answer:
The attribute that overrides character encoding in web development is the charset attribute in the meta tag of an HTML document.
Step-by-step explanation:
Character Encoding and Overrides
In the context of web development, the attribute that overrides character encoding is the charset attribute in the meta tag of an HTML document. This attribute specifies the character encoding to be used when displaying the document.
For example, the following meta tag overrides the default character encoding to use UTF-8:
<meta charset="UTF-8">
By specifying a charset encoding, you can ensure that special characters and international characters are displayed correctly in a webpage.
