National flags in Windows fonts

Context

This gist contains a copy of my comment to a Medium article named Designing in the Open(Source) published by Microsoft Design (official account).

The article is about Fluent Emoji -- a collection of emoji from Microsoft. They are kind of a big deal because they are included with every copy of Windows operating system as a Segoe UI Emoji font.

Datastore is weird!

It is a legacy service tied to App Engine. Once enabled, App Engine API cannot be disabled on a Cloud project.

Cloud projects can use either Datastore or Firestore but not both. Once set, it cannot be changed. Since all legacy App Engine apps use Datastore, a different project must be used for Firestore usage.

This Codelab gives some historical context on App Engine, Datastore, and Firestore.

For Python client for Datastore API there are at least two options:

# -*- coding: utf-8 -*-
"""
This script was written to solve a specific problem:

A large directory of video files had file names encoded in Windows-1251.
These file names would not display correctly in Windows 10 or OS X.
I wanted to recode them to the native encoding for the current file system.
Python is smart enough to apply the correct encoding when writing out
the file names to the file system.
