The author seems to ignore the fact that CSV got so popular because it is human readable. If anyone wanted a binary format there’s plenty of them - most better than this DSV.

Also, I’m on a mobile right now, so can’t verify that, but it seems the format is flawed. The reader decodes UTF8 strings after splitting the binary buffer by the delimiter, but I believe the delimiter may be a part of a UTF8 character.

Edit: just checked and there’s actually no chance that the delimiter the author chose would be part of UTF8 encoding of any other character than the delimiter itself
