Adding Sterling pound character when the Keybord does not have it!

Some times computer keybord does not contains some characters such as sterlin pound sign, euro sign,omega sign etc.
The easiest way to get this in windows is using charmap command.

In windows run or command prompt type charmap and enter. You will get the character map window with lot of symbols.
Now only thing you have to do is select the symbol you need to copy it and paste where you want.
Enjoy!
