This little tool generates s̶t̶r̶i̶k̶e̶t̶h̶r̶o̶u̶g̶h̶ text using unicode characters. While the text it generates may look similar to text generated using the <strike> HTML tag or text-decoration:line-through CSS attribute, it isn't*. You can use this script to generate strikethrough text to paste in to Twitter or Facebook, or to register internationalized domain names containing strikethrough characters (ie. s̶t̶r̶i̶k̶e̶.ws).**
*If you copy & paste this
HTML generated strike into a text document or a HTML form field, the text decoration attribute won't stick (unless you're pasting into an WYSIWYG HTML editor). However, if you copy and paste this U̶N̶I̶C̶O̶D̶E̶ ̶g̶e̶n̶e̶r̶a̶t̶e̶d̶ ̶s̶t̶r̶i̶k̶e̶, the text decoration will persist regardless.
Result (you can copy and paste this):
s̶t̶r̶i̶k̶e̶ ̶i̶t̶ ̶l̶i̶k̶̶e̶ ̶i̶t̶s̶ ̶h̶o̶t
