Hi,
I tried using decoding part of code, but couldn't get working decode, so it decodes:
String stru = "c8SBbHM=";
It returns "sÄ�ls", but it should return "sāls", it is probably some problem with UTF-8.

I also tried to incorporate some conversion from bytes to String but still I'm stuck.

Encoding part is working fine with UTF-8, thank you very much.
