Dear all,
Is there a quick and easy way of converting utf characters to the \uxxxx
form (necessary e.g. for packages)? I mean something working like this:
utf2uxxxx("õäöü")
[1] "\u00f5\u00e4\u00f6\u00fc"
It is easy to program but perhaps someone already has implemented this. (I
couldn't find anything useful from searches incl RSiteSearch).
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.
