+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.
