[ESS] Utf-8 problems

[Serdae]

Hi,

I'm running ESS for MacOSX 10.6.8 and have problems with setting the 
locales for sv_SV.UTF-8 permanent.
For instance running the following command gives
 > paste("åäö")
[1] "\303\245\303\244\303\266"

sessionInfo()
R version 2.15.0 (2012-03-30)
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)

locale:
[1] C

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

loaded via a namespace (and not attached):
[1] compiler_2.15.0 tools_2.15.0

Regards Serdar
