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

Hi Tim,
Yes, I wrote the codepage_def file.
It does the correct thing:
i -> \230
\215 -> I
for Turkish. This is not where the problem is. Filenames get
displayed/written etc. correctly. The above capitalization is as it should
be for Turkish.

According to SMB protocol, are share names supposed to be ASCII only?
If this request came from the Windows world for HULUS\230, there would be no
problem. Instead it (someone, either Samba or Windows, I guess more likely
windows?) takes hulusi and mangles it according to ASCII, not codepage 857,
resulting in HULUSI. Then, samba takes over and mangles HULUSI according to
codepage 857, resulting in the non-symmetrical case (hulus\215).
Whereas in filenames, the mangling works correctly -- request comes in
mangled according to codepage 857, samba mangles it according to codepage
857 and we are all happy.
This is not a simple codepage bug I am talking about, I wish it were, it
would be simple and within my immediate reach to fix. If you'll bear with
me, below is a full explanation of the problem.
I am including two cases:
1. Case that does not work: Turkish i's in shares.
2. Case that works: Turkish i's in filenames.
For filenames, Windows requests and receives the correct i'd name: --> for a
small dotted i, it asks for italy.gif, Samba looks and finds italy.gif or
\230taly.G\230F
For sharenames, Windows does not seem to request the correct i'd name -->
for a small dotted i, (share name [hulusi]), it should have asked for hulusi
or HULUS\230 . Instead, it asks for HULUSI, which in Turkish codemap is a
different character, so samba can't find it.
Below is log fragments etc. for these two cases.
Please give me some ideas where to look for this stuff in the code. I am
willing to work on this problem, I need guidance as to where it happens.
Best regards,
Deniz
Case that does not work: Turkish i's in shares:
1. We have samba codepage 857 running
2. We create a samba share [hulusi]
3. We list samba services available we see: \\samba01\hulusi
4. We try to request this share (click on it in NT explorer) -- get error
that "The network name cannot be found"
5. We look at samba logs:

Now is the working stuff, with filenames.
Case that works: Turkish i's in filenames:
1. We have samba codepage 857 running.
2. We create a samba share [foo]
3. We see this samba share from the NT world: \\samba01\foo
4. We put into this share, two files:
italy.gif
\230test.rtf (\230 being capital dotted i)
5. We access these from NT --> works fine.
6. We look at samba logs.
