TLDR; Из-за всяких неотображаемых символов юникода становится возможно закодировать произвольные данные в обычный смайлик (да и вообще в любой юникод символ). При этом закодированная часть не теряется даже при пересылке эмодзи!
Интересно, какой максимальной длины сообщение можно так передать? Можно ли так передать целый файл? 👀󠇀󠆒󠇁󠅻󠄐󠇁󠅷󠇁󠅲󠇀󠆮󠄐󠇁󠅲󠇁󠅳󠇁󠅲󠄐󠇁󠅱󠇀󠆠󠇀󠆬󠇁󠅻󠇀󠆩󠄐󠇀󠆫󠇁󠅾󠇀󠆡󠇀󠆮󠇀󠆯󠇁󠅻󠇁󠅲󠇀󠆭󠇁󠅻󠇀󠆩󠄯

Emerson Brooking, a disinformation expert at the Atlantic Council's Digital Forensic Research Lab, said: "Back in the Wild West period of content moderation, like 2014 or 2015, maybe they could have gotten away with it, but it stands in marked contrast with how other companies run themselves today." "Someone posing as a Ukrainian citizen just joins the chat and starts spreading misinformation, or gathers data, like the location of shelters," Tsekhanovska said, noting how false messages have urged Ukrainians to turn off their phones at a specific time of night, citing cybersafety. As the war in Ukraine rages, the messaging app Telegram has emerged as the go-to place for unfiltered live war updates for both Ukrainian refugees and increasingly isolated Russians alike. Crude oil prices edged higher after tumbling on Thursday, when U.S. West Texas intermediate slid back below $110 per barrel after topping as much as $130 a barrel in recent sessions. Still, gas prices at the pump rose to fresh highs. The War on Fakes channel has repeatedly attempted to push conspiracies that footage from Ukraine is somehow being falsified. One post on the channel from February 24 claimed without evidence that a widely viewed photo of a Ukrainian woman injured in an airstrike in the city of Chuhuiv was doctored and that the woman was seen in a different photo days later without injuries. The post, which has over 600,000 views, also baselessly claimed that the woman's blood was actually makeup or grape juice.
