[R] Correct Localized Numbers on Plots, related to glibc!

I have read that. And I have used the standard way of changing locale
to fa_IR.utf8 (i.e. using
Sys.setlocale(category="LC_ALL",locale="fa_IR.utf8"). Also
Sys.setlocale(category="LC_NUMERIC",locale="fa_IR.utf8") )  The output
of Sys.localeconv at the end of my email should have made this clear.

The result is the same on RStudioGD, X11, pdf, ps, cairo_pdf,
cairo_ps, svg, png, jpeg, bmp. (I do not know if this is what you are
asking for. if not let me what exactly you are asking and how can  I
find it please.)
My sessionInfo is as follows:

R version 2.14.1 (2011-1-22)
Platform: i486-pc-linux-gnu (32 bit)

locale:
 [1]  LC_CTYPE=fa_IR.utf8			LC_NUMERIC=fa_IR.utf8
 [3]  LC_TIME=fa_IR.utf8				LC_COLLATE=fa_IR.utf8
 [5]  LC_MONETARY=fa_IR.utf8		LC_MESSAGES=en_US.UTF-8
 [7]  LC_PAPER=C					LC_NAME=C
 [9]  LC_ADDRESS=C				LC_TELEPHONE=C
[11]  LC_MEASURMENT=en_US.UTF-8	LC_IDENTIFICATION=C

attached base packages:
[1] stats	graphics	grDevices	utils	datasets	methods	base

loaded via a namespace (and not attached):
[1] tools_2.14.1

 I have read the posting guide. I had not posted the sessionInfo as
the information on system and graphic device seemed irrelevant, as it
does not change in different devices and also on Microsoft Windows
the locale Persian_Iran.1256 does not change anything. I have not
talked about windows as I don't expect windows to do anything
correctly on Persian.

Well, I assume that changing the locale should do the trick, but it
does not. As I mentioned earlier:
X11()
Sys.setlocale(category="LC_ALL",locale="fa_IR.utf8")
Sys.setlocale(category="LC_NUMERIC",locale="fa_IR.utf8")
plot(gdpr)
