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

[Majid Einian]

Dear R Helpers,

I want to localize my plots, i.e. the numbers by x & y axis be
Persian, using Persian numerals and Persian decimal separator. I
change the locale to fa_IR.utf8, but nothing on plots change. I can
change the numerals shaping to Persian ones (۱۲۳۴ instead of 1234)
using some non-standard fonts but the decimal point is a problem. I
asked about that in Persian-Computing mailing list and I got the
answer that follows. I don't know how should I use this "l" flag
mentioned in the answer in R plots (I'm using simple R plots, no
special library).

Has anybody had similar problem in any language (maybe Arabic, other
languages I'm not sure use different numeral characters).
Also I don't have e.g. French locale on my system to see if the
decimal separator changes accordingly to locale for them.

Thanks in advance.

The glibc model for generating numbers is kind of complex. For using
native digits, one is supposed to use the "I" flag. For example, in
order to get ۱۲٫۳, you should do printf("%I.1f", 12.3).

This is to make sure applications have a way to output both ASCII
numbers, and native numbers.

 I have found that decimal seperator in fa_IR.utf8 is . (dot), I
thought it should be U+066B , any comments or ideas why it is not so?
