I think that it's necessary to prepare the Wide-version in reality.
However, AdaCore seem they are thinking Ada's File API take Unicode
filename.

I do not care this point if it works correctly.

But, these API implementation is not making sense of the meaning.
It is possible to think "Character" type based Unicode filename to
UTF-8.
Actually, it is locale-character-code(Shift_JIS in Japanease-ver.
Windows, LC_xxx environment-variable in Linux...when locale is UTF-8 by
chance, it is likely to operate according to the
intention.) that Ada.Text_IO.Create accepts.
Also, Ada.Directories.Validity takes correct-filename as error.
Confusion and mistake seem in each place.

Therefore, I consider this a bug in GNAT.
Thank you for teaching the report destination.
