Topic: Are lost characters
We have such basis
In the register nls_lang RUSSIAN_CIS.CL8MSWIN1251
It was required to write, it is impossible while even to deduce, somewhere
select to_nchar (' '), ' ', to_nchar (' '), dump (to_nchar (' ')) from dual;
??????? ?? ?? Typ=1 Len=4: 0,63,0,63
With RUSSIAN_CIS.AL32UTF8 too most.
All right to show on the screen that dump (to_nchar (' ')) shows that there questions most of all guards.
What I do not so?
