The client code set

When the Informix® ESQL/C processor creates a file whose file name has non-ASCII characters, the client locale must support these non-ASCII characters.

Before you start the HCL Informix database server, you must ensure that the code set of the client locale (the client code set) contains these characters.

When you use a nondefault locale, you must set the CLIENT_LOCALE environment variable to the name of a locale whose code set contains these non-ASCII characters.

For example, suppose you want to process the Informix ESQL/C source file with the path /A1A2B1B2/C1C2D1D2, where A1A2, B1B2, C1C2, and D1D2 are multibyte characters in the Japanese SJIS code set. You must perform the following steps to enable the esql command to create the intermediate C source file on the client computer:
  1. Set the CLIENT_LOCALE environment variable on the client computer to the Japanese SJIS locale, ja_jp.sjis.
  2. Process the Informix ESQL/C source file with the esql command.
If the code sets that are associated with the file name and with the client locale do not match, a valid file name might contain invalid characters with respect to the client locale. The Informix ESQL/C processor rejects any file name that contains invalid characters and the following error message is displayed:
Illegal characters in filename.
