Though I practice I type double space after full sentences and when
there's a single space and small letters.

    (defun rasmus/org-latex-filter-nobreaks-double-space (text backend info)
        "Tries to export \"S1. S2\" as \"S1.\\ S2\",
       while letting \"S1.  S2\" be exported without tilde"
        ;; TODO: error with this output:
        ;; [[file:nasty dir/Screenshot. from 2015-03-05 19:05:00.png]]
        (when (and text (org-export-derived-backend-p backend 'latex))
          (let ((preamble (or (string-match-p "\\\\begin{document}" text) 0))
                (case-fold-search nil))
            (concat (substring text 0 preamble)
                    (replace-regexp-in-string "\\. \\([^ A-Z\n]\\)"
                                              ".\\\\ \\1"
                                              (substring text preamble))))))

                 'rasmus/org-latex-filter-nobreaks-double-space)

Or,

    (defcustom rasmus/org-latex-unicode-to-tex  '((" " "~")
                                                (" " "\\,")
                                                ("​" ""))
      "list of re rep pairs which are replaced during latex export")

    (defun rasmus/org-latex-unicode-to-tex (text backend info)
      "Replace unicode strings with their TeX equivalents.

  Currently:  ' ' (no break space) to '~'

      (when (org-export-derived-backend-p backend 'latex)
        (cl-loop for (re rep) in rasmus/org-latex-unicode-to-tex do
