National Language Support (NLS) is responsible for Character
and language conversion according to the configured language.
With the support of NLS, BTT applications are able to display in
different languages according to customers' requirements without further
translation. This is because a NLS element consists of a value and
a key. Different languages refer to different values while they share
the same key.

below.
