My display name on Twitter currently looks like @ɢᴇᴏʀɢᴇᴠʀᴇɪʟʟʏ@ᴛᴇᴄʜ.ʟɢʙᴛ, an attempt to route around Twitter’s apparent censorship of Mastodon in­for­ma­tion.

I used the FSymbols Generators to produce several variants.

@𝕘𝕖𝕠𝕣𝕘𝕖𝕧𝕣𝕖𝕚𝕝𝕝𝕪@𝕥𝕖𝕔𝕙.𝕝𝕘𝕓𝕥
ʇqƃʅ.ɥɔǝʇ@ʎʅʅᴉǝɹʌǝƃɹoǝƃ@

@𝔤𝔢𝔬𝔯𝔤𝔢𝔳𝔯𝔢𝔦𝔩𝔩𝔶@𝔱𝔢𝔠𝔥.𝔩𝔤𝔟𝔱

Many of these variants come from Unicode Block “Math­e­mat­i­cal Al­phanu­mer­ic Symbols”.

There are a lot more things you can do with Unicode than just upside-down text.
