Comment (by kkmuffme):

 I know, but the problem is that this can accidentally make a plugin break
 another plugin or WP core alltogether with a fatal error.


 e.g. plugin A:
 {{{#!php
 <?php
 function my_cb_a( $value ) {
     if ( isset( $_GET['foo'] ) && current_user_can( 'administrator' ) ) {
         return 'UTF-8';
     }

     return $value;
 }
 add_filter( 'pre_option_blog_charset', 'my_cb_a' );
 }}}

 plugin B:

 {{{#!php
 <?php
 function my_cb_b() {
     $example = get_option( 'blog_charset' );
 }
 add_action( 'plugins_loaded', 'my_cb_b' );
 }}}
