When the system variables @@debug_dbug was assigned to some expression, Sys_debug_dbug::do_check() did not properly convert the value from the expression character set to utf8. So the value was erroneously re-interpretted as utf8 without conversion. In case of a tricky expression character set (e.g. utf16le), this led to unexpected results. Fix: Re-using Sys_var_charptr::do_string_check() in Sys_debug_dbug::do_check().
