| <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. |
