[BEAM-1674] Add unicode type to the typeDict attribute in Python SDK
When I executed Biq Query exection on the Google Cloud Dataflow, the
following error occurred.
```
UnicodeEncodeError: 'ascii' codec can't encode characters in position
73-78: ordinal not in range(128)
```
It seems there is a problem when the executed SQL is UTF-8 strings(unicode
type).
```python:apache_beam/transforms/display.py
#TODO: Fix Args: documentation once the Python classes handling has
changed
type_ = cls.typeDict.get(type(value))
if type_ is None:
type_ = 'CLASS' if inspect.isclass(value) else None
if type_ is None and value is None:
type_ = 'STRING'
return type_
```
so unicode type is always considered as None type.
So I fixed the problem the following code.
