Translation:What is this character?
I feel like this would have been a better lesson to learn in the beginning of the course, and not 700 characters into the language
Does this question imply asking for details (the way this english translation implies), or is the implication more like you just need a little reminder (in which case it would be more like "what character is this?").
I think this question is asking for detail. For a reminder, I would say "这个是什么字来着？", kind of like "what is this character again?"
No characters available and I do not have a Chinese keyboard. Report options do not allow for this problem.
You'll have to download your own Chinese keyboard. Duolingo does not provide one.
"What does this character mean?" should be accepted (is the more normal English way to express this meaning!)
