Codex:

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();
