What does Unicode fonts specifically address?

Unicode fonts specifically address the mapping of glyphs to code points in a standard. Unicode is a character encoding standard that allows for consistent representation and manipulation of text across different systems and platforms. By assigning a unique code point to each character, emoji, or symbol, Unicode enables the proper display and interchange of text in various languages and scripts, ensuring that users can read and write text correctly regardless of the software or hardware being used.

This standardization is crucial for accessibility and compatibility purposes, particularly for documents and applications that need to support multiple languages and character sets. Such an approach helps to prevent issues related to character misrepresentation or loss of meaning when text is transferred between different systems.

In contrast, the other options do not address the core purpose of Unicode. Decorative fonts may enhance aesthetics in design but are not related to Unicode's primary function. The use of text in video formats and the creation of computer animations fall outside the scope of what Unicode addresses, which is fundamentally about text representation rather than visual or multimedia content creation.
