Editors and code views should definitely show when BiDi and other interesting Unicode features are used, just like they already do with spaces and zero-width whitespaces. These features should definitely work, but they are a liability if they can also used to mislead human users. Compiler maintainers need to update the syntax rules to restrict free mixing of unicode characters. Similar restrictions were already adopted in domain names.
