<em><code class="parameter">encoding</code></em> is the character encoding name
used for the HTTP input character encoding conversion, HTTP output
character encoding conversion, and the default character encoding
for string functions defined by the mbstring module.
You should notice that the internal encoding is totally different from the one for multibyte regex.

If <em><code class="parameter">encoding</code></em> is set, then
Returns <strong><code>TRUE</code></strong> on success or <strong><code>FALSE</code></strong> on failure.
In this case, the character encoding for multibyte regex is NOT changed.
If <em><code class="parameter">encoding</code></em> is omitted, then
the current character encoding name is returned.
