For non-English languages it is unusual, but according to Knuth, it is tradition in professional English typesetting to increase (though usually not double) the amount of space between sentences: That's why some additional space is TeX default if you do not switch the behaviour off with \frenchspacing (the latter being default in many non-English languages). For details concerning fixed-width typewriters, I know only the tradition of my country which is \frenchspacing... I guess the section about French/English spacing in https://en.wikipedia.org/wiki/History_of_sentence_spacing is rather exhaustive. >> > Could that be triggering something ? >> > I'm using Seamonkey set to send plain text to anything Gentoo related. >> >> IIRC HTML defaults to collapse double spaces to single [...] > > KMail also has an option to collapse double spaces to one. Since it is "forbidden" to collapse nonbreakable space, I guess that the seamonkey editor transforms additional spaces (maybe only if occurring after punctation signs) to nonbreakable space to make sure that it is not lost in display. You need a special editor/mode (like emacs) to optically distinguish breakable (\x20) and nonbreakable (\xa0 = \x20 | \x80) space.
