Thanks @wvengen for pointing to this mistake and @fsmanuel for the clearification. You are right of course. I will change the English locale in a minute.

For German, I prefer the guillemet style ([which is also official German](http://www.belleslettres.eu/artikel/typografie-anfuhrungszeichen.php)), because it is unprobable that the user types it on his keyboard. This helps to avoid ugly messages like

    Neuer Lagerartikel „Apfel "Jonagold"“ erstellt.

or even

    Neuer Lagerartikel "Apfel "Jonagold"" erstellt.

in favor of

    Neuer Lagerartikel »Apfel "Jonagold"« erstellt.

Should we discuss about stuff like this before introducing to the German local?
