There seems to be a bug in the WORD Index.

Hello, I'm writing a document with an index.  There are several Latin based names that require symbols, most notably a small e with an acute accent.  The problem name is "Vélez."  It will not index correctly putting a separate line for each entry.  In troubleshooting the problem, I find that if I replace the symbol "é" with "e," it works okay.  Interestingly, the name "Frémont" works okay too.  Any ideas?
