#! /usr/bin/env python3
#
# Fixes encoding of the project files to add UTF-8 BOM.
#
# Visual Studio insists on having the BOM in project files, and will
# restore it on first edit. This script will go through the relevant
# files and ensure the BOM is included, which should prevent too many
# irrelevant changesets.
