Unicode Binary Input Terminal

I love this project - a rack-mounted keyboard device that lets you input any Unicode codepoint (character) using toggle switches, complete with a visual preview. Works for Emoji too and looks beautiful.

BjÃ¶rn HÃ¶hrmann's excellent compact UTF-8 decoder is one of those C masterpieces that makes you realize quite how powerful the language can be.

today i've mostly been reading about surrogates (for the noted2 unicode library) and have finally tracked them down in the unicode manual. it seems like a poorly designed part of unicode, which should have just been replaced by utf32.
