Didn't know that 16:13:57 <shelikhoo> and basically one need to known that language the text is in to render it correctly 16:14:02 <shelikhoo> the same before unicode 16:14:05 <dcf1> shelikhoo: yes, the percent-encoding is the only reasonable thing to do for interchange of URLs, it's just not so nice to look at 16:14:56 <shelikhoo> I didn't see any discussion about ECH in the ntc party link 16:15:34 <shelikhoo> I could try if such blocking can be reproduced on vantage point 16:17:33 <shelikhoo> anything more we would like to discuss about this topic? 16:19:25 <shelikhoo> anything more we would like to discuss in this meeting? 16:19:37 <onyinyang> nothing from me 16:20:59 <shelikhoo> thanks! we could discuss the tls1.3 censorship topic again once we have more data 16:21:01 <shelikhoo> #endmeeting
