Commit 2b3d04787012 ("unicode: Add utf8-data module") changed the
database file from 'utf8data.h' to 'utf8data.c' to build separate
module, but it seems forgot to update Documentation/dontdiff. Remove
'utf8data.h' and add 'utf8data.c'.

I'll apply this, but does anybody actually use the dontdiff file
anymore?  I think it's old and, if being used, actively harmful; for
example, it masks changes to "parse.c", an instance of which was added
to git in January.

Is there a reason to not just remove this file?

Thanks,

jon

Completely agree，It seems fs/unicode module missing to update `dontdiff`
I've actually never used it, seems that developers likely using .gitignore.
eg. 98f2345773f（"unicode: fix .gitignore for generated utfdata file")
