[ROS2] UnicodeEncodeError building test_msgs as an overlay on Windows

Hey Forum,

I'm working on the ros2_dotnet project (language bindings for C#). Currently the build instructions require a full rebuild of the core ROS2 repositories, and I'm working on converting that to be an overlay on top of an existing ROS2 installation (requires the core ros2_dotnet repositories and any packages containing interface definitions).

I'm finding that when I build certain messages (for example the test_msgs package) I get a UnicodeEncodeError.

Here's a minimal repos file (referred to as 'minimal.repos' below)

repositories:
  ros2/rcl_interfaces:
    type: git
    url: https://github.com/ros2/rcl_interfaces.git
    version: eloquent
  ros2/rosidl_defaults:
    type: git
    url: https://github.com/ros2/rosidl_defaults.git
    version: eloquent
  ros2/test_interface_files:
    type: git
    url: https://github.com/ros2/test_interface_files.git
    version: eloquent

I have installed the binary package for ROS2 Eloquent to c:\dev\ros2e. My commands, run from an Administrative VS2019 developer prompt:

call \dev\ros2e\setup.bat
md c:\dev\test_ws\src
cd c:\dev\test_ws
vcs import src < minimal.repos
colcon build --merge-install --packages-up-to test_msgs

Building test_msgs fails with the following output:

This does not reproduce using the same minimal.repos file on Linux, or if I build the entire ROS2 source tree (of course without sourcing the underlay).

Have I stumbled upon a bug or is there something more obvious I'm doing wrong?

It seems like rebuilding the rosidl package as well avoids this, but I don't think that should be necessary to generate new interface bindings.
