Description:
Creating a table with a name containing multibyte characters results in an SDI file name where all characters after the first mb char has been omitted.

How to repeat:
let $MYSQLD_DATADIR = `select @@datadir`;
CREATE TABLE tæøå(i INT) ENGINE MYISAM;
--list_files $MYSQLD_DATADIR/test

Suggested fix:
Make sure that char values are cast to unsigned char before being passed to my_mbcharlen(CHARSET_INFO*, uint).
