Anki fails to import from .csv file

I have created an custom note type containing 3 fields: Character, Pinyin and Definition. I have a .csv file containing a few entries. The fields are comma-delimited.

Here's what I am presented when I try to import the file:

The mapping looks fine.

And here's how Anki fails to import:

Apparently it doesn't import anything at all. So, to debug I reduced my file to this:

爸爸,bàba,papa dad father
杯子,bēizi,cup glass
北京,běijīng,Beijing (Peking)

That's right, even importing these 3 lines fails.

So what is wrong?
