I just prepare upgrade from NW6 -> NW 6.5 and during tests I realized that
CIFS users used to write their files in Unicode code page. However, NCP
client does not support it, so if any national character is in
file/directory name, it is not visible by netware klient (NCP). In NW6
there was checkbox in C1 to turn off Unicode on CIFS shares and then
national characters in file/directory names worked OK.
In NW 6.5 this checkbox dissappeared in iManager, but still is present in
C1; unfortunately does not work.

How to turn off Unicode on CIFS shares?

My users work with both protocols so the problem is rather arduous; I
can't do upgrade untill all have access to their files.
