A form is displayed with invalid characters

You may have different codesets on the client workstation and the application server.

The typical mistake that can happen is the following: You have edited a form-file with the encoding CP1253; you compile this form-file on a UNIX-server (encoding ISO-8859-7). When displaying the form, invalid characters will appear.

This is usually the case when you write your source file under a Windows® system (that uses Microsoft™ Code Page encodings), and use a Linux® server (that uses ISO codepages).

Keep in mind that all source files must be created/edited in the encoding of the server (where fglcomp and fglrun will be executed).
