The Web’s Missing Language Enablement Data: From Script Requirements to Browser Behavior

Fuqiao Xue

This presentation explores what it takes for a writing system to work well on the web and ebooks after its characters have been encoded. Unicode provides the foundation, but users also need browsers, fonts, layout engines, CSS, authoring tools, and digital publishing systems to understand how their text should behave. The talk will show how language enablement data, including script requirements, typographic conventions, gap analyses, and community feedback, helps connect Unicode encoding to real-world Web behavior. The topic connects directly to UTW 2026’s theme, Unicode in the World. Many communities, especially those using less widely supported writing systems, still face problems with line breaking, justification, segmentation, ruby-like annotations, and other layout behaviors. These issues are often not Unicode problems alone, but cross-layer problems involving standards, implementations, and community knowledge. Audience members will gain a clearer understanding of how script and language requirements are gathered, documented, and translated into actionable improvements for web standards and browser behavior. They will also learn how Unicode specialists, font developers, browser engineers, standards editors, and language communities can collaborate more effectively to close support gaps.
