function drupal_strtolower($text) { global $multibyte; if ($multibyte == UNICODE_MULTIBYTE) { return mb_strtolower($text); } else { // Use C-locale for ASCII-only lowercase $text = strtolower($text); // Case flip Latin-1 accented letters $text = preg_replace_callback('/\xC3[\x80-\x96\x98-\x9E]/', '_unicode_caseflip', $text); return $text; } }

There are more problematic places in that file, besides the one mentioned here. For example, I just run into:

Deprecated: mb_strlen(): Passing null to parameter #1 ($string) of type string is deprecated in /includes/unicode.inc on line 482

referring to:

function drupal_strlen($text) { global $multibyte; if ($multibyte == UNICODE_MULTIBYTE) { return mb_strlen($text); } else { // Do not count UTF-8 continuation bytes. return strlen(preg_replace("/[\x80-\xBF]/", '', $text)); } }
I encountered the error when adding a new action (adding a variable) into a rule, when clicking "Switch to data selection". The error appears in a JS dialog window.
