UnicodeDecodeError with non-ASCII characters in message definition

[moooeeeep]

I have custom message definitions that contain UTF-8 encoded characters in the comments. When I try to filter topics from bagfiles that contain these messages, it fails with UnicodeDecodeError.

I already described it here:

• unicode support (ros ticket #4053) ros_comm#143 (comment)

And linked to a related entry in the ROS Q&A:

• https://answers.ros.org/question/240612/rosbag-unicodedecodeerror/

On my machine I could work around this by removing the call to .encode() in the line highlighted in the Traceback:

• https://github.com/ros/genpy/blob/kinetic-devel/src/genpy/dynamic.py#L168

I don't know what other side effects this may produce (maybe with other file encodings of the message definition?), but so far it seems to work...
