Twitter accepts the UTF-8 codes which works out well considering we only get 140 characters. It can also make your micro-blog more interesting and artistic.
Until now, though it has been tough to remember all those codes (unless you were an Uber-geek). Now The Next Web has provided this handy Twitter Key that is in a floating window.
You simply double-click then copy and paste into your tweet!
Go to their blog HERE and click to bookmark the TwitterKey.
Great job, guys!
