Links with Non-ASCII: Unicode Detection and Display
The standards for URLs and their implementations in browsers generally handle Unicode quite well, permitting people around the world to use their writing systems in those URLs. But link detection and display is a different story; almost all implementations do that badly; causing significant problems for users of non-ASCII characters — and the problems are not limited to domain names. This presentation discusses the problems for users, and then how https://www.unicode.org/reports/tr58/ sets out to fix them.
