Correct. It's done by the function `org-export-solidify-link-text'. The
problem is that it isn't used consistently across the back-end. It
should be fixed now.

You may use \nbsp{} entity.

My keyboard layout allows for easy access to non-breaking spaces. So
I use the following instead (_ character stands for the non-breaking
space):

#+begin_src emacs-lisp
(defun ngz-latex-filter-nobreaks (text backend info)
  "Ensure \"_\" are properly handled in Beamer/LaTeX export."
  (when (memq backend '(e-beamer e-latex))
    (replace-regexp-in-string "_" "~" text)))
(add-to-list 'org-export-filter-plain-text-functions
             'ngz-latex-filter-nobreaks)
#+end_src

HTH,
