Figure 55. UNIVERSAL Input Method: Character List 10.5.5 Codeset Conversion Tables As more code sets are supported, it becomes important not to clutter programs with the dependency of any particular code set. This is known as code set independence. To aid in code set independence, NLS supplies converters that translate character encoding values found in different code sets. Using these converters, a system can accurately process data generated in different code set environments In addition to Unicode, a number of new 8-bit codesets have been proposed that will contain the Euro symbol. Although AIX will not have supported locales in many of these code sets, it will provide data conversion capabilities to, and from, these code sets. The new code sets that are being introduced are as follows: • IBM-1252 (extended) - This code set will be used by the Euro single-byte (SBCS) migration option. • IBM-858 - This code set is identical to IBM-850 except that the dotless letter i, which is used only in Turkish, is replaced with the Euro symbol. This code set will be used in OS/2. • IBM-114x - Ten new code sets are being introduced that serve the same function as the existing EBCDIC code sets, except that one character is replaced with the Euro. The new code sets are summarized in Table 55. Table 55.

The UCSTBL method is located in the /usr/lib/nls/loc/uconv directory and loads UCS-2 (Unicode) conversion tables created by the uconvdef command. In order to compile the UCS-2 (Unicode) conversion table, the uconvdef command reads a source file that defines a mapping between the UCS-2 and a particular multi-byte code set. The source files are in the /usr/lib/nls/uconv table directory with names that are composed of the code set name appended by the suffix .ucmap. The UCSTBL method uses the table to support UCS-2 conversions in both directions. The setup of a converter is complete if the proper symbolic links for conversions in each direction are created in the /usr/lib/nls/iconv directory. For example, the links for the conversion of the IBM-850 code set to UCS-2, and vice versa, are defined as shown below: # cd /usr/lib/nls/loc/iconv # ln -s /usr/lib/nls/loc/uconv/UCSTBL IBM-850_UCS-2 # ln -s /usr/lib/nls/loc/uconv/UCSTBL UCS-2_IBM-850 The Universal_UCS_Conv method is located in the /usr/lib/nls/loc/iconv directory and can be used to convert between any two code sets whose conversions to, and from, UCS-2 are defined. The conversion is instantiated by setting the proper links. Assuming that someone wants to define the conversion of the IBM-850 to, and from, the UTF-8 code set, you would have to enter the following sequence of commands: # cd /usr/lib/nls/loc/iconv # ln -s /usr/lib/nls/loc/uconv/Universal_UCS_Conv IBM-850_UTF-8 # ln -s /usr/lib/nls/loc/uconv/UCSTBL IBM-850_UCS-2 # ln-s /usr/lib/nls/loc/uconv/UCSTBL UCS-2_UTF-8 # ln -s /usr/lib/nls/loc/uconv/UCSTBL IBM-850 # ln -s /usr/lib/nls/loc/uconv/UCSTBL UTF-8 As you can see from the example above, UTF-8 converters are usually done by using the Universal_UCS_Conv and the /usr/lib/nls/loc/uconv/UTF-8 conversion. It should be noted that, for some conversion pairs, a substitution character may be inserted when converting a Euro symbol from a codeset that contains the Euro to a codeset that does not (For example: Converting IBM-114x to ISO8859-1).
