Unicode support: LANG env variables is not getting passed

When I connect with usual ssh and type some Cyrillic letters it's ok, but when I connect via ssh3 and try to type something Cyrillic, the command line just brakes, only one letter make it broken.

Also when I try to list a directory with files not in standard ASCII symbols, is shows quite strange escaped characters.
`ls -la` command gives me something like this:
```
