While several character encodings like ASCII or ISO 8859-1 exist, UTF-8 is the most widely used standard today. It supports a vast range of characters, including diverse languages, symbols, and special characters, ensuring consistent rendering across all platforms.

Objectives

• Ensure all characters are encoded using the UTF-8 standard to prevent display issues.
• Guarantee accurate character representation across different devices and reading systems.

Implementation

• Configure production tools and databases to use UTF-8 as the default character encoding.
• Set the charset attribute of the meta tag to UTF-8.

Control

• Check the source code of the EPUB’s HTML pages: ensure that the tag with the charset attribute is set to UTF-8 and is located within thesection.
