Comment (by dmsnell):

 @garrigan I would be reluctant to add random type checks to this function
 whose documentation already indicates that `$text` ought to be a string.
 if anything, if we want to perform the runtime type-checking we would want
 to ask for what we want rather than what we don’t want, e.g. `if ( !
 is_string( $text ) ) { return ''; }`

 it appears, however, that the problem is likely higher up in the call
 stack; something is calling `wp_check_invalid_utf8()` improperly. are you
 able to to log what this is?

 if you are able to recreate the error condition then you can temporarily
 modify the WordPress file to get out the data and call stack.

 {{{#!php
 <?php
 function wp_check_invalid_utf8( $text, $strip = false ) {
         if ( is_array( $text ) ) {
                 var_dump( $text );
                 throw new Error( 'should only be passing string; not array
 to wp_check_invalid_utf8()' );
         }

         $text = (string) $text;
         …
 }}}
