Spacing issues with alternative keyboards

[oguzkocer]

A user reported that the editor is adding an extra space before a punctuation. Another user reported that they are using Swift keyboard and the editor is deleting the space before it. Let's investigate the different Android keyboards a bit and see if we can replicate any of it. /cc @aforcier

I'm more inclined to think that this is a Samsung (or Samsung + custom keyboard) issue than a simple custom keyboard one, as the editor has been tested with most of the popular custom keyboards out there (including SwiftKey) with no issues like this.

I couldn't replicate it with Google Keyboard on my S6, but maybe it only happens on other custom keyboards as you mentioned.
