Logtalk - Object oriented extension to Prolog
Release 2.25.1

To load this example and for sample queries, please see the SCRIPT file.
This is a very simple example of using the new, experimental encoding/1
directive, which is fully based on the directive with the same name found
on recent development releases of SWI-Prolog. Currently, this example
requires Logtalk to be run with the SWI-Prolog compiler.
The "babel.lgt" source file uses UTF-8 encoding. The "latin.lgt" source
file uses ISO-8859-1 (Latin 1) encoding. Be sure to use a text editor that
supports these encodings when opening these files. In addition, you may
need to configure your text editor to open the source file using the
declared encoding. If you are using the SWI-Prolog GUI application on
Windows, be sure to select a font which supports Unicode characters.
Currently, Logtalk accepts any atom is an argument for the encoding/1
directive. As, by default, Logtalk automatically generates a XML documenting
file for each compiled entity, the following table is used to set the
encoding of the XML file:
Logtalk source file XML file
ascii us-ascii
iso_latin_1 iso-8859-1
unicode_be utf-16
unicode_le utf-16
utf8 utf-8
Note that the values on the left column are the ones recognized by SWI-Prolog.
