To access the Character Map in Vista or Windows 7, click on Start and enter character map into the search box and hit Enter.
Now choose the font which matches what you’re working in, select the special character you want to use.
Then just paste the character into your document, online form, or whatever app you need to use it in.
If you want to navigate to it via the Start Menu, go to Start \ All Programs \ Accessories \ System Tools \ Character Map.
Another way to quickly pull it up is to enter charmap or charmap.exe into the run line.
This “oldie but goodie” feature should help out those new to Windows, and perhaps some users who have forgotten about it.
