Cycles is enabled per default. Please try File -> Load Factory Settings and enable Cycles via the Info Header.

It was enabled but it isn't in info header. And when i import project with cycles settings it just go on blender render there is no cycles.

Is it because mbcs is used not UTF8?
Is it a cause that file path is not encoded?

Deveoper note:

While it looks like a regression, masqueraded issue was present in previous releases. It is caused by use of PyUnicode_EncodeFSDefault() to deal with file paths. While it worked fine for single-byte characters it fails for multi-byte ones. So old behavior was simply silent failure and unable of use of CUDA/OSL, new behavior is that Cycles fails to register at all (this seems to be related on internal check that built-in functions does not fail when running python bindings).

Not sure yet what would be the real solution here, but simple fix for upcoming 'a' release wuould be to call PyErr_Clear() if PyUnicode_EncodeFSDefault() fails.
