luatex problem with file with umlauts on windows 10

[Zdenek Wagner]

Hi all,

looking at:

(./test-utf8.tex (./grüße.tex)
FILE:   ./grüße.tex
SIZE:   nil
isfile  false

I have three questions:
1. What is your locale of your Windows? Is it UTF-8?
2. Which character set is used for file names on your file system?
3. Are you sure that lfs knows the character set of your file system
(you should query it) and that the file name is corrected to the right
encoding?
