Actually, shouldn't the whole file be converted to NFC, instead of
only identifiers? If you have decomposable characters in strings and
your editor decides to normalize them to a different form than in the
original source, the meaning of the code will change when you save
without you noticing anything.

It's always better to be explicit when you want to make invisible
distinctions. In the rare cases anything but NFC is really needed you
can do explicit conversion or use escapes. Having to add normalization
calls around all unicode strings to code defensively is neither
convenient nor obvious.
