Consider using -isnoconv when all of the following conditions occur:

A 4GL program contains character variables initialized from text literals.
The text literals contain international characters (whether or not the literal is flagged as untranslatable using the :U attribute).
The code page of the r-code (-cprcodein) does not match the code page of internal memory (-cpinternal).
This is a compile-time option, not a run-time option, and affects the generation of r-code, not its execution.

When you run earlier versions of Progress under these conditions, and Progress reads text literals from r-code into internal memory, it does not convert the code page. To compensate for this, programmers often pre-convert international characters in text literals to -cpinternal.

When you run Version 9.1A under these conditions, and Progress reads text literals from r-code into internal memory, it converts the code page from -cprcodein to -cpinternal. This code page conversion might cause international characters you have pre-converted to -cpinternal to be converted again to -cpinternal, which garbles them.

Note: Progress Software Corporation recommends that you avoid preconverting text literals.
