This somewhat makes sense as it mentions the page content itself was in French. However then "solving" the problem by making a domain with both languages hyphenated only magnifies the issue more - to indicate an expectation you should know both languages. Any logical personal will understand showing content in multiple languages (as text output); but when it comes to user text input (domains, web search etc), it's absurd to believe the same rules should apply for the user.
