Code-page conversion tables

A code-page conversion table tells OpenEdge how to convert a character on one code page to the equivalent character on another code page. OpenEdge uses a code-page conversion table when:

  • You convert a database and its data to a different code page. For more information on converting a database to a different code page, see Rules and Techniques for Databases.
  • OpenEdge automatically converts data from one code page to another during execution. For more information on automatic code-page conversion, see About Code Pages.

The following figure shows a code-page conversion table for converting from code page 1256 to code page 709. Code pages 1256 and 709 are used in locales that use the Arabic language. This table resides in the arabic.dat file.

A code-page conversion table contains a value for every element in the code page. Values appear in rows of sixteen. Each value represents the corresponding element in the target code page. For example, as the figure shows, element 240 in code page 1256 corresponds to element 235 in code page 709.
