Tail End Charlie - Or how to make an Outlook Category (and Windows Explorer folder) sort out at the bottom of a list.
Jonathan Hardwick did a post on "Outlook 2007 folder and category names - what's the sort order" [Here] but did not provide a "funny character" that sorts out at the end of list.
One solution is the Greek capital letter omega "Ω" Unicode 03A9. Which you can input under Windows by holding down the ALT key while typing 1002 on the numeric keypad.
This fix is Code Page dependent. And if you use it for Windows folders or file names, some programs (e.g. UltraEdit) will barf when you try to open them.
