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', 'wp_kama_pre_get_col_charset_filter', 10, 3 );
