[BUG] Fixing frequent Python errors when using operations.

[emmambd]

Describe the bug
I get the following recurring bugs when I follow the steps in Installation and Adding feeds

To Reproduce
Steps to reproduce the behavior:

1. Use internal Linux virtual machine (MobilityData specific step)
2. Follow Installation instructions up to and including source env/bin/activate
3. Run from tools.operations import *
4. Get: ModuleNotFoundError: No module named 'gtfs_kit'

If I rerun the pip install -r requirements.txt command outside the Python VM, then rerun from tools.operations import * I get a new error: UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 3131: invalid start byte

Expected behavior
No error returned after from tools.operations import *

Hello,
I was countering the same issue but it seems changing the opening statement in the tools/representations.py solved the problem.

Specifically, you can replace the line 91 in that script which now is
with open(os.path.join(path, file)) as fp:
To
with open(os.path.join(path, file), encoding='utf-8') as fp:
This solved the problem for me as it avoiding the UnicodeDecodeError by indicate the correct encoding format.
