Non-breakable spaces should be treated as usual spaces

Hello!

We're trying to move our tests from SeleniumLibrary to Selenium2Library. But we've found that our tests are failing on checks upon elements that contain non-breakable spaces (which works fine with SeleniumLibrary).

Here I provide the simplest test case that demonstrates that behavior. I have no fix yet, but I'll try to provide it ASAP. Maybe you can suggest the way I should follow to fix this (it would be great!).
