py3 issues about omero-scripts HOT 2 CLOSED

From the former issue it looks like we need to specify utf-8 encoding wherever appropriate similarly to ome/omero-py#110. Looking at https://python-future.org/compatible_idioms.html#file-io-with-open, it might be possible to have a unified Py2/Py3 idiom:

from io import open
...
    with open(file_name, 'w', encoding='utf-8') as csv_file:
...

The latter issue is related to the fact the omero-metadata plugins needs to be upgraded to Python 3 - see in-progress work in ome/omero-metadata#36

from omero-scripts.

There was a workaround in d9119de to only write encoded bytes to csv, because writing unicode to csv fails on the py3-ci server due to lack of UTF-8 encoding as described ome/omero-figure#343 (comment) and ome/omero-figure#351 (comment)

from omero-scripts.
