Hi, everyone!
I have kept trying upload groups by a csv file within a course, and finally I found that if the csv file is English Letter only, if works fine. But if my groupname is in Chinese or with any Chinese Characters, it fails, and keep telling me that the "groupname" namefield is invalid.
Since the csv file can't be saved in UTF-8, so any solution for this issue? Any suggestion? I have more than 20 courses and 30 groups for each. Manually adding the group would be a nightmare
