is_utf8_charset() │ WP 6.6.0

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".
$is_utf8 = is_utf8_charset();

Хуков нет.
