Description
Indicates if a given slug for a character set represents the UTF-8
text encoding. If not provided, examines the current blog's charset.A charset is considered to represent UTF-8 if it is a case-insensitive
match of "UTF-8" with or without the hyphen.
Example:
true === is_utf8_charset( 'UTF-8' );
true === is_utf8_charset( 'utf8' );
false === is_utf8_charset( 'latin1' );
false === is_utf8_charset( 'UTF 8' );
// Only strings match.
false === is_utf8_charset( [ 'charset' => 'utf-8' ] );
// Without a given charset, it depends on the site option "blog_charset".
