11.4 Charmap and Oracle Character Set
The character set mapping (charmap) of the locale ID assigned for each language may vary depending on the distribution and version of the Linux operating system. To determine the current character mapping, enter the following command in a shell:
% locale charmap UTF-8
Table 6 lists each charmap with its corresponding Oracle character set. In general, you should update the CHARACTER_SET part of the NLS_LANG parameter according to the actual charmap of your Linux session.
