Антон Бауткин:

I have changed code page in my cmd to 65001 (it's utf-8), and while installing sqlalchemy by pip:
```
c:\Program Files\Python35\Scripts>pip3.exe install sqlalchemy
```
I obtained next error:
```
Collecting sqlalchemy
  Using cached SQLAlchemy-1.1.3.tar.gz
Installing collected packages: sqlalchemy
  Running setup.py install for sqlalchemy ... error
Exception:
Traceback (most recent call last):
  File "c:\program files\python35\lib\site-packages\pip\compat\__init__.py", line 73, in console_to_str
    return s.decode(sys.__stdout__.encoding)
  File "c:\program files\python35\lib\encodings\cp65001.py", line 17, in decode
    return codecs.code_page_decode(65001, input, errors, True)
UnicodeDecodeError: 'CP_UTF8' codec can't decode bytes in position 0--1: No mapping for the Unicode character exists in the target code page.

During handling of the above exception, another exception occurred:

    return s.decode('utf_8')
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xed in position 34: invalid continuation byte
```

To solve this, change you code page to 866 
```
chcp 866
```

And try to install sqlalchemy once again.
