Ubuntu Linux Alt Numpad Codes
In Ubuntu the alt+numpad ACSII codes don’t work - this was a major stumbling block for me since I have a few passwords that contain special characters. After too much time Googling I found that if you hold Ctrl+Shift+U you can then release the “U” key (while still holding Ctrl+Shift) and begin to type the Unicode code for the special character you’d like to use. A cross reference of characters is available at the Ultimate Cool Characters site - it seems fairly comprehensive (the unicode is the ‘Character Code’ on the site).
