Font validation is a feature in Font Book that helps identify and resolve issues related to duplicate fonts. When you run the font validation process, the application will scan for duplicates and notify you of any conflicts. This is particularly important because having duplicate fonts can lead to inconsistencies in how text displays, potentially causing confusion during document creation or graphic design projects.

By validating fonts, Font Book not only detects duplicate entries but also helps users manage their font collections more effectively, allowing them to deactivate or delete redundant fonts. This ensures a cleaner, more organized font library and maintains the integrity of the fonts being used across applications.

The other options, such as font compression, conversion, and archiving, do not specifically address the issue of duplicate fonts, making them less relevant in this context. Font compression relates to reducing file size, font conversion deals with changing font formats, and font archiving is about storing fonts for future use rather than resolving conflicts.
