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();源码
function is_utf8_charset( $blog_charset = null ) { $charset_to_examine = $blog_charset ?? get_option( 'blog_charset' ); /* * Only valid string values count: the absence of a charset * does not imply any charset, let alone UTF-8. */ if ( ! is_string( $charset_to_examine ) ) { return false; } return ( 0 === strcasecmp( 'UTF-8', $charset_to_examine ) || 0 === strcasecmp( 'UTF8', $charset_to_examine ) ); }
