Shapecatcher looks up Unicode symbols based on a drawing of the symbol. It is conceptually similar to Detexify, but returns Unicode symbols instead of macros.
The tool converts an input string into different and sometimes obscure Unicode characters. It is usefull to generate funny looking text or to generate a new username, if the desired on is taken.
For example, the tool supports ⓒⓘⓡⓒⓛⓔⓓ, 𝖋𝖗𝖆𝖐𝖙𝖚𝖗, 🆂🆀🆄🅰🆁🅴🅳, ꜱᴍᴀʟʟ ᴄᴀᴩꜱ, ɐup 𝕠𝕥𝕙𝕖𝕣 wɘiᴙb options.
