Work on TrueCrypt encrypted volumes is not supported?

Recuva factually does not work on TrueCrypt encrypted volumes. Almost all found deleted files (either on encrypted system volume or in file containers) marked as 'Excellent' recover incorrectly, part of recently deleted files can not be found, and so on. Nice program, but looks like not for TC users. Pity. Any plans to fix that? Or any solutions may be?
