textfac.es (or textfaces or text faces, I'm not really sure either and the words in these parentheses are really only here for SEO ( ͡° ͜ʖ ͡°)) lets you finally write those damn unicode faces. You should probably bookmark it so you don't lose it. Or just google "textfaces" every time look I don't care I'm not the boss of you. When you need a textface, just hit the bookmark, click the face, and paste it where you want it to go.
How does the click-to-copy work?
The click-to-copy works through ZeroClipboard, which uses Flash (I'm so sorry). If you don't have Flash, you'll have to highlight the faces like a caveman.
Some of them look kinda weird.
If the faces look weird or you see rectangles all over the place, you might not have the right fonts installed. Or the face might actually be weird.
