Identifying a Unicode character

[David J. Perry]

Listmembers,

If I receive a Word document created with a font I don't have, and my 
Unicode fonts (even Lucida Sans Unicode or Arial Unicode) don't have that 
character, is there any way to find out what Unicode value underlies the 
little rectangle that is displayed?  Then I could look up the value and 
find out what the character is supposed to be.  I know how to get Word to 
convert a hex number into a real Unicode character--but can one do the reverse?

Thanks -- David
