DVM locale settings in .xcf files

The locale settings for the DVM must be defined in the application .xcf files.

Setting a DVM locale is described in the chapter on Application locale in the Genero Business Development Language User Guide.

On Linux®/UNIX™, the DVM locale is defined by the LC_ALL environment variable. On Windows®, the DVM locale is defined by the LANG environment variable.

The DVM locale configuration must be defined in the application specific .xcf file, with the ENVIRONMENT_VARIABLE element.

Note: If the application connects to an SQL database, make sure to define the database client locale. The next examples show how to set the Informix® client environment variables CLIENT_LOCALE and DB_LOCALE.

Example with UTF-8 locale settings in Linux:

Note: When using a UTF-8 locale, consider using char length semantics, with FGL_LENGTH_SEMANTICS=CHAR.

Example with UTF-8 locale settings in Windows:

Note: The Microsoft® C runtime setlocale() ".utf8" code page name is supported starting from Windows 10 build 17134 (April 2018 Update). For older Windows versions, use the BDL UTF-8 fallback ".fglutf8".
