Update head.cin

Add %gen_inp as required. This now works on OSX with Yahoo KeyKey (and probably OpenVanilla), after removing manually line 13967 (the very last line) of `result.cin` which is an unencoded `佛`.


Also some lines that seems off:

```
-o 耶穌
```

Also `lo̍kㄌㆦㆶ̍ 落 lo̍hㄌㄜㆷ̍` are encoded as `o`?
