I understand you very well. I can try to look at Apache source codes and
recompile it with some changes.
Otherwise, thank you for your time. I'm trying to resolve this for three
days :-D
Have a nice day,

Hi.
I do not know the answer precisely either.
But I know enough to tell you that in such matters, you must be
/extremely/ careful in interpreting what is really going on, at each
level.
Just as a stupid example : when you look at a log file, you must know
: - has the process that writes that logfile transformed the data into
some encoding already, when writing it to the logfile ?
- is the editor which I am using aware of the logfile encoding ?
etc...
Because otherwise what you see, and what is really there, may be
different things.
For example, I think I remember that, internally, in the Windows NTFS
filesystem, file names are stored as Unicode (not necessarily UTF-8,
it could also be UTF-16 or another Unicode encoding).
(See for example here : http://www.ntfsrecovery.com/a-ntfs.php)
But when you look at a directory through the Explorer, these internal
filenames /may/ get transformed according to your PC's codepage, just
to display it to you.
So what you think you see, is not necessarily what is really there.
Understand what I'm saying ?
Just some elements :
- Apache should not "translate" or "encode" the received URL, because
basically it does not know if this URL is in UTF-8, ASCII, or any
other encoding. There is no "flag" or "header" in a HTTP request, that
says in which encoding the "GET" line comes in. (e.g. it may also be
some Japanese or Chinese encoding).
So it /must/ take it as bytes.
- then Apache calls the OS to find the file. There may, or may not,
be some translation there, I really don't know. It may depend on what
API call the program uses to read the directory, and I don't know what
Apache uses.
- it's the same for your C program. I don't know if the OpenFile()
call interprets "name" as a pure byte sequence, or if it converts it
internally, or whatever.
- and we don't know if Apache and your program use the same API calls.
For example, in Java or Perl, there are different ways to open a file
and to read/write from it, some with encoding/decoding going on, some
not. Unfortunately, I am incompetent in C and Windows API, so I don't
know in that case.
Obviously something is happening somewhere, and obviously it happens
differently under Unix and under Windows.
Under Unix/Linux, most of these things are influenced by the "locale"
under which the process is running. Under Windows, it is usually the
whole system-wide "International settings" which count.
I think we need an Apache/Windows developer here, to really tell us
what is going on.
