IBM Conversion Mapping Tables

IBM has a repository of character data mapping tables between many different character encodings and Unicode. The mapping of some characters in the IBM conversion tables may vary from those of other vendors. These differences may be due to differences in interpretation of international or country standards. They may also be due to historical product or platform preferences. IBM conversion tables are available from a number of sources.

Unicode mappings can be found in the International Components for Unicode (ICU) which is a mature, portable set of C/C++ and Java libraries for Unicode support, software internationalization (I18N) and globalization (G11N), giving applications the same results on all platforms.

Additionally, IBM has the Character Data Representation Architecture (CDRA) which defines a set of identifiers and supporting resources for data identification and conversion. The CDRA conversion table resources can be obtained from IBM developerWorks. The tables are found in the Downloads & products view, under the heading Character Data Conversion Tables.
