<p>Although I wouldn't really know why you would like to use these 
features, they are provided for ISO compliance.

<dl class="latex">
<dt class="pubdef"><span class="pred-tag">[ISO]</span><a id="char_conversion/2"><strong>char_conversion</strong>(<var>+CharIn, 
+CharOut</var>)</a></dt>
<dd class="defbody">
Define that term input (see <a id="idx:readterm3:1160"></a><a class="pred" href="termrw.html#read_term/3">read_term/3</a>) 
maps each character read as
<var>CharIn</var> to the character <var>CharOut</var>. Character 
conversion is only executed if the Prolog flag <a class="flag" href="flags.html#flag:char_conversion">char_conversion</a> 
is set to
<code>true</code> and not inside quoted atoms or strings. The initial 
table maps each character onto itself. See also <a id="idx:currentcharconversion2:1161"></a><a class="pred" href="charconv.html#current_char_conversion/2">current_char_conversion/2</a>.
</dd>
<dt class="pubdef"><span class="pred-tag">[ISO]</span><a id="current_char_conversion/2"><strong>current_char_conversion</strong>(<var>?CharIn, 
?CharOut</var>)</a></dt>
<dd class="defbody">
Queries the current character conversion table. See <a id="idx:charconversion2:1162"></a><a class="pred" href="charconv.html#char_conversion/2">char_conversion/2</a> 
for details.
