It is not a big deal as long as seemingly identical file names are treated by OS as different.<p>Unicode normalization is not the only problem here, e.g. Latin &#x27;a&#x27;, &#x27;e&#x27;, &#x27;T&#x27; are exactly the same as Cyrillic &#x27;а&#x27;, &#x27;е&#x27;, &#x27;Т&#x27; in most fonts which makes it possible for two files to have seemingly same names even in some 8-bit encodings.
