One can also use the Mac OS character palette, which is available in many programs by selecting Special Characters from the Edit Menu, or from the Input Menu (flag) icon on the menu bar (enabled in the International section of the System Preferences).
In Microsoft Windows, one can type Alt 248 or Alt 0176, or one can use the Character Map tool to obtain a graphical menu of symbols.
