and Windows 98 value. This will provide some level of compatibility for Windows
clients running AIX server applications.
While all code page 1252 graphics will be processed correctly, the AIX font set
will only be extended to support the Euro symbol not the additional unique
graphics in code page 1252. Customers selecting this approach are cautioned to
review display requirements for 1252 graphics.
Furthermore, assigning characters to the ASCII control points in the code page
1252 can be a significant problem for customers who use ASCII terminals or have
applications that use ASCII terminal emulators. Trying to use ASCII terminals
with the Euro symbol will require additional customization such as fonts or INOUT
transforms, or will be limited to the existing non-euro character sets. AIX provides
terminal definition tables that may have to be modified depending on the usage.
Since AIX locales can be changed based on an application basis, the only
applications to be reviewed for potential customization are those applications that
require ASCII terminal input and/or ASCII terminal emulation support and must
handle the Euro at the same time.
Usage of the SBCS migration option will require the use of the fully qualified
locale and code set name, as follows:
For example, in order to use the German locale with the Euro SBCS migration
option, the user would set LANG=de_DE.IBM-1252. This would provide the
proper code set environment for the Euro character but would still format
monetary quantities in the traditional national currency format. In order to specify
Euro currency formatting, the user would additionally set
LC_MONETARY=de_DE.IBM-1252@euro.
Keyboard mappings, including the Euro and bound to IBM-1252, are provided as
links to the related ISO keyboard maps.
Although SBCS migration option locales are bound to IBM-1252, full font support
for the additional group of characters in IBM-1252 that is not currently defined in
ISO8859-1 (other than the Euro) is not guaranteed, nor is it guaranteed that all
existing ISO8859-1 fonts will be extended to include the Euro or additional
characters. At a minimum, the set of fonts corresponding to the Common Desktop
Environment (CDE) dt aliases for IBM-1252 (such as "-dt-interface system-*" and
"-dt-interface user-*") are enhanced to include the Euro.
Documentation is provided that will instruct customers who are using IBM-850
based locales how they can achieve Euro support on AIX by creating their own
customized locale using the localedef facility. Refer to AIX Version 4.3 Base
Documentation and AIX Version 4.3 Extended Documentation.
10.5.7 Packaging
Each Unicode based locale listed in Table 51 on page 256, and commonly
referred to by XX_XX in this paragraph, is separately installable and contains the
complete set of function to provide both traditional monetary as well as Euro
monetary formatting. All locale specific modules are separately installable and
are grouped and distributed in two different entities:
• bos.loc.utf.XX_XX fileset
• X11.loc.XX_XX package comprised of the filesets:
