Handle   inserted by browser instead of spaces.

When typing, browsers insert   char whenever it is needed to correctly display inserted space. Since we decided that we want to keep view and model clean, we don't want those  s. This means, that we need to get clean them.

Are you talking about sequences of spaces? If so, it may not be in the model, but it's certainly a requirement in the view.

It's definitely not a requirement in the view. The view format independent. Subsequent spaces may be differently rendered depending on a data format, so it DP's role to render them as it wishes.
