Release 10.1A: OpenEdge Development:
Internationalizing Applications

Code-page conversion

As data flows between application components that have different code pages, OpenEdge sometimes converts the data from the code page of the source component to the code page of the destination component. This is illustrated in Figure 2–6.

Figure 2–6: Code-page conversion

For each line in Figure 2–6, OpenEdge might:

Convert the code page no matter which direction the data is flowing in.
Convert the code page if the data is flowing in one direction, but not the other.
Not convert the code page.

To convert data from one code page to another, OpenEdge uses a code-page conversion table. OpenEdge supplies a collection of code-page conversion tables in the DLC/prolang directory. You can also create your own code-page conversion tables. For more information on code-page conversion tables, see Chapter 3, " Understanding Character Processing Tables." For more information on code-page conversion and databases, see Chapter 6, " Using Databases." For more information on code-page conversion and SQL, see Chapter 7, " Using SQL."
