And depending on the use of \nonfrenchspacing and \frenchspacing.

This could easily be turned off with the use of a single \frenchspacing
in the preamble (or in the document; you may switch between the two in
the document as often as you like; e.g. \frenchspacing is active
starting from the point TeX reads the macro until it is set back to
\nonfrenchspacing).
