Problem with Turkish character share names -- how to modify?

[Deniz Akkus Kanca]

I realize re-reading my earlier message that it is quite confusing:

Ascii case transform:       i      -> I

Turkish dotted i transform:     i   -> \230
Turkish dotless i transform:     \215 -> I

So, when Samba receives request for HULUSI, it does the right thing by
looking for:
    HULUSI
    hulus\215

The sharename being  hulusi (and appearing that way for the Windows 857
client), the request for hulusi should have come as:
    hulusi
or HULUS\230

Ways of getting correct behaviour would be:

1. Getting windows to either preserve case during the sharename request, or
do the correct charmap (ask for HULUS\230, this being the correct
transformation for codepage 857) transformation, instead of doing it
according to ASCII.

2. If it is samba that does not preserve case (receive hulusi, transform it
to HULUSI), extend that portion of it to do international codepage specific
transformations instead of ASCII as it seems to be doing. (IF it is the
party at fault -- ie if it is receiving hulusi and transforming it to
HULUSI)

3. If it is indeed windows that is at fault, or the SMB protocol does not
preserve case, or something of that sort that Samba does not control --
meaning samba gets request for HULUSI and does the best it can by correctly
transforming it to hulus\215 and looking for it that way -- then, Samba
could have a workaround in the Turkish case, for the dotted/dotless i cases
where it looks for the other i .

The 3rd would be a workaround. The pair (i,\230) is distinct from (\215,I)
pair in Turkish and a word would be considered different if it had i vs.
\215.  It would cover every case, except when a sharename is different only
by virtue of dotted i vs. dotless i, so I guess it would work the great
majority of the time. Windows shares can be created with dotted i's and
dotless i's and be distinct, so I am hoping that it is not the Windows
portion of the communications that is going awry (also because it would be
impossible to change)..

Sorry for the longish message.

Best regards,
Deniz
