iconv() may be able to do it; the only caveat is that it is not part of 
R, and may vary from system to system.  On my Mac,

iconv("õäöü", to="C99")

gives

"\\u00f5\\u00e4\\u00f6\\u00fc"

so you'd get what you want with

cat('"', iconv("õäöü", to="C99"), '"', sep="")


However, on Windows, C99 is not a supported value for the destination 
encoding, so I think you'd have to program it via conversion to raw 
bytes.  Or maybe there's another function out there that I don't know about.
