GAS system encoding

System character encoding matters when Genero Application Server (GAS) interacts with the operating system.

For example, GAS uses the character encoding set by the operating system when it performs the following:

  • Writes log files.
  • Opens files defined in the GAS configuration file (as.xcf).
  • Reads arguments from the command line.
In these cases and more, GAS uses the character encoding set by the operating system environment:
  • Linux®/UNIX™: encoding is defined via environment variables LANG or LC_ALL. For more information see the "Localization" topics in Genero Business Development Language User Guide or see The Single UNIX - Specification Version 2 - Locale.
  • Windows®: GAS defaults to the system locale as defined in the language and regional settings.
    Note: There should be no need to set the LANG variable, except your application uses a different character set to the Windows system locale.

How GAS does character set conversion

The GAS software takes care of character set conversions:
  • For xcf files, it does the conversion based on what the XML prolog specifies as charset to the GAS locale, for example:

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>

  • For the front-ends such as Genero Browser Client (GBC) that use UTF-8 encoding:
    • The charset in the metadata of the bootstrap.html file is used. For more information, see the Genero Browser Client User Guide.
    • For the DVM the conversion is done in the DVM locale, see DVM locale settings in .xcf files.
