AIX Version 4.3 Differences Guide

Any UTF-8 based locale installed on an AIX system will provide the desired
support for the Euro symbol. For those countries that may have to actively use
the Euro (Table 51 on page 256), the locales will deliver the input methods and
the keyboard maps required to enter the Euro symbol through the keyboard. For
the same group of countries, an additional LC_MONETARY locale is available to
enable the Euro currency formatting. This locale is identified by the suffix @euro.
For example, if you are using the UTF-8 locale DE_DE, which specifies German
language and territory, and your system is configured for Euro currency
formatting, then the locale command will return the following output:
# locale
LANG=DE_DE
LC_COLLATE="DE_DE"
LC_CTYPE="DE_DE"
LC_MONETARY="DE_DE@euro"
LC_NUMERIC="DE_DE"
LC_TIME="DE_DE"
LC_MESSAGES="DE_DE"
LC_ALL=
The related locale definition source files and the locale databases can be found in
the /usr/lib/nls/loc directory:
# cd /usr/lib/nls/loc
# ls -l DE_DE* | egrep -v "\.[il]" | cut -c55-
DE_DE -> /usr/lib/nls/loc/DE_DE.UTF-8
DE_DE.UTF-8
DE_DE.UTF-8.src
DE_DE.UTF-8@euro
DE_DE.UTF-8@euro.src
DE_DE.UTF-8@euro__64
DE_DE.UTF-8__64
DE_DE@euro -> /usr/lib/nls/loc/DE_DE.UTF-8@euro
DE_DE@euro__64 -> /usr/lib/nls/loc/DE_DE.UTF-8@euro__64
DE_DE__64 -> /usr/lib/nls/loc/DE_DE.UTF-8__64
The locale database for the DE_DE locale is actually an alias for DE_DE.UTF-8,
and likewise, the database for the DE_DE@euro locale is linked to
DE_DE.UTF-8@euro. Note, you should not use the referenced locale databases
DE_DE.UTF-8 and DE_DE.UTF-8@euro explicitly as parameter to the chlang
command or as variable value for LANG. The names of the locales are aligned to
the traditional AIX locale naming convention.
Since a locale is a loadable object module, a different object is required when
running in the 64-bit environment. Consequently, you find one 64-bit enabled
locale database for any 32-bit locale database. The 64-bit databases are readily
identified by the __64 suffix. In the 64-bit environment, the application will
automatically append __64 to the name of the locale when searching for the
proper NLS.
The locale definition source files hold the suffix .src and belong to the separately
installable bos.loc.adt.locale fileset.
10.5.2.1 Euro Sign Character Classification
For each UTF-8 based locale, the Euro sign was added as a valid graphical and
printable character. The Euro sign is not classified as an alphabetic, upper or
lower case letter, nor a numeric symbol.
