pre_get_table_charset filter-hook . WP 4.2.0

Filters the table charset value before the DB is checked.

Passing a non-null value to the filter will effectively short-circuit checking the DB for the charset, returning that value instead.

Usage

add_filter( 'pre_get_table_charset', 'filter_function_name_7555', 10, 2 );
function filter_function_name_7555( $charset, $table ){
	// filter...

	return $charset;
}

$charset(string|null)

The character set to use.
Default: null

$table(string)

The name of the table being checked.

Where the hook is called

$charset = apply_filters( 'pre_get_table_charset', null, $table );
