Removal of single byte character set conversion for front-ends

Starting with version 2.32, the FGLPROFILE entry gui.chartable is no longer supported. This entry could be used to make the runtime system convert GUI data to the character set of the front-end.

The built-in charset conversion is not needed if you are using the correct locale corresponding to the character set used by your application and database with the LANG / LC_ALL environment variables.

To simplify the upgrade process to 2.32, the feature is still available, but it will be removed in a future version.
