Hereʼs what I tested 20d1 a⃑ 20d2 a⃒ 20d3 a⃓ 20d4 a⃔ 20d5 a⃕ 20d6 a⃖ 20d7 a⃗ 20d8 a⃘ 20d9 a⃙ 20da a⃚ 20db a⃛ 20dc a⃜ 20dd a⃝ 20de a⃞ 20df a⃟ 20e0 a⃠ 20e1 a⃡ 20e2 a⃢ 20e3 a⃣ 7⃣ 20e4 a⃤ 20e5 a⃥ 20e6 a⃦ 20e7 a⃧ 20e8 a⃨ 20e9 a⃩ 20ea a⃪ 20eb a⃫ 20ec a⃬ 20ed a⃭ 20ee a⃮ 20ef a⃯ 20f0 a⃰ 20f1 a⃱ 20f2 a⃲ 20f3 a⃳ 20f4 a⃴ 20f5 a⃵ 20f6 a⃶ 20f7 a⃷ 20f8 a⃸ 20f9 a⃹ 20fa a⃺ 20fb a⃻ 20fc a⃼ 20fd a⃽ 20fe a⃾ 20ff a⃿ (I think 20f1-20ff are actually codepoint non grata, but I canʼt find the reference for the moment) gedit combines some of them, but not others. It does not use the emoji font for 0037 20e3, though, you need to add fe0f in the middle for that to happen. libreoffice combines more, but not the same set as gedit. It does however render 0037 20e3 with the emoji font. Screenshots below. Robert --
