Search and Replace an Extended Character ?

[jclements]

Is there a way to search and replace a character (which is an extended character) using the "u+####" code? The character would typically be part of a string of characters.

For instance, find all instances of a Star character and replace it with a Box character (or a character from the keyboard)?

I know you can cut and paste a character into the find and replace dialog which is a two step process (once for the find field and the other for the replace field) but I hoping for a way to enter the "U=####" code like you can with ASCii character codes via holding the Alt key using the numeric keypad.
