Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Like most PHP functions, substr() is not multibyte-aware. You may prefer to use 
mb_substr() instead.
