System message about incoming buzz is incorrectly escaping spaces

Description

When someone send a buzz (nudge) to a user, in receiving user's chat window it shows a system message that another user is seeking your attention. In that message it adds \20 instead of spaces in a name of a user sending buzz and also uses lowercase, even if name has uppercase letters.
