<dd>
|
<p><code>SELECTED_CHAR_KIND(NAME)</code> returns the kind value for the character
|
set named <var>NAME</var>, if a character set with such a name is supported,
|
or <em>-1</em> otherwise. Currently, supported character sets include
|
“ASCII” and “DEFAULT”, which are equivalent, and “ISO_10646”
|
(Universal Character Set, UCS-4) which is commonly known as Unicode.
