pre_get_col_charset filter-hook . WP 4.2.0

Filters the column charset value before the DB is checked.

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

Usage

add_filter( 'pre_get_col_charset', 'filter_function_name_2839', 10, 3 );
function filter_function_name_2839( $charset, $table, $column ){
	// filter...

	return $charset;
}

$charset(string|null)

The character set to use.
Default: null

$table(string)

The name of the table being checked.

$column(string)

The name of the column being checked.
