Sieverules plugin have config setting for this:
// Sieve RFC says that we should use UTF-8 endcoding for mailbox names,
// but some implementations does not covert UTF-8 to modified UTF-7.
// set to null for default behaviour
$sieverules_config['folder_encoding'] = 'UTF-8';

As I know, others implementations leak this feature, so you should hack sources.
