mon cher oncle, 
I know and use dpkg-reconfigure locales, just I always thought that this is the way to set system locale, while I need set locale per user; I want, for example, that Luna Lovegood, user luna, logs in with full italian DE; Fleur Delacour (user fleur) with full french DE and Lavender Brown (user lavender) with full german DE.
I’ve done a test, on a QEMU VM freshly installed choosing Italian in installer language menu, so having a brand new user with italian DE (everything, applets like fuzzyclock included):
I’ve created another user, Sylvie Vartan (user commeungarcon
) and after login I’ve changed DE locale from Region and Language from Italian (that came as standard) to french; re logging-in DE was a mix between Italian and French (see screenshot here)
/home/commeungarcon directories were all still in italian (no screenshot because I don’t want bother you all with a bunch of screenshots).
Then I add export LC_ALL=fr_FR.UTF-8
to .profile, logged-out and re logged-in and finally everything (home directories and fuzzyclock included) were in french. Notice that login screen was still in italian, since system locale is italian.
Finally I created another user, Melantho Kallipareos (user melantho) whose DE at login was in italian, then I gave dpkg-reconfigure locales
from terminal seting el_GR as default, logged-out and re logged-in (this time login window was in greek) and finally everything was in greek in melantho DE (except for fuzzyclock that I suppose is missing greek translation).
But when I logged in as Sylvie Vartan (french DE), after having commented out “export LC_ALL=fr_FR.UTF-8” in .profile, I found a mess between greek and french.
Finally: if someone wants to configure locales per user, export LC_ALL=xx_XX.UTF-8" in .profile is mandatory; doing a dpkg-reconfigure locales changes system locale, so previous workaround still remains mandatory for having a fully localized DE.
Thanks for your patience in reading all this …
Sil

- Just for your knowledge, Melantho (better, Μελανθώ with acute accent on final omega, described as καλλιπάρῃος, nice cheeks) is one of Penelope’s favourite maidens, who in Odyssey is accused of traison and hanged by Thelemacus … when I was a little girl, I watched at Odyssey in TV and cried for her: that’s why she is my favourite character!)
