DM's suggestion of using the Perl facility is fine, and I use it myself 
plenty often when I'm scripting Perl. But there's also an ICU utility 
which can achieve normalization (and much more).

uconv (meant as a replacement for iconv, if you're familiar with that) 
does codepage/encoding conversion, transliteration, and normalization. 
It's part of the standard ICU distribution and we have Windows binaries 
on the FTP site:

(I'd recommend the big, 7.6 MB version of the ICU data for this.)

Use is fairly straightforward, but to take a file "input" and NFC 
normalize it as a file "output" you would use (assuming both are UTF-8):

uconv -f utf-8 -t utf-8 -x NFC -o output input
