+	<p>Sets the range of characters that the system will consider printable in heuristic detection of strings. This typically affects the shell, debugger and io:format functions (when ~tp is used in the format string).</p>

+	<taglist>
+	  <tag><c>latin1</c></tag> <item>The default. Only characters
+	  in the ISO-latin-1 range can be considered printable, which means
+	  that a character with a code point &gt; 255 will never be
+	  considered printable and that lists containing such
+	  characters will be displayed as lists of integers rather
+	  than text strings by tools.</item>
+	  <tag><c>unicode</c></tag>
+	  <item>All printable Unicode characters are considered when
+	  determining if a list of integers is to be displayed in
+	  string syntax. This may give unexpected results if for
+	  example your font does not cover all Unicode
+	  characters.</item>
