ASCIIfy() - a proposal for package:tools
Nobody else has replied to this, so I will. It's very unlikely that we would incorporate this function into base R. For one thing, the tools package is intended to be tools used by R, not by users. R doesn't need this function, so it doesn't belong in tools. (Some other functions in tools like showNonASCII have come to be used by users, but their primary purpose is for R.) Utility functions that are maintained by R Core and are useful to users belong in the utils package. But I wouldn't add ASCIIfy to that package either, because I don't want to impose its maintenance on R Core. Utility functions that are maintained by others belong in contributed packages. So I'd suggest that you add this function to some package that you maintain (perhaps a new one, containing a collection of related utility functions), or search CRAN for an appropriate package with a maintainer who is willing to take this on.

Hi all, I would like to propose the attached function ASCIIfy() to be added to the 'tools' package. Non-ASCII characters in character vectors can be problematic for R packages, but sometimes they cannot be avoided. To make packages portable and build without 'R CMD check' warnings, my solution has been to convert problematic characters in functions and datasets to escaped ASCII, so plot(1,main="S?o Paulo") becomes plot(1,main="S\u00e3o Paulo"). The showNonASCII() function in package:tools is helpful to identify R source files where characters should be converted to ASCII one way or another, but I could not find a function to actually perform the conversion to ASCII. I have written the function ASCIIfy() to convert character vectors to ASCII. I imagine other R package developers might be looking for a similar tool, and it seems to me that package:tools is the first place they would look, where the R Core Team has provided a variety of tools for handling non-ASCII characters in package development. I hope the R Core Team will adopt ASCIIfy() into the 'tools' package, to make life easier for package developers outside the English-speaking world. I have of course no problem with them renaming or rewriting the function in any way. See the attached examples - all in flat ASCII that was prepared using the function itself! The main objective, though, is to ASCIIfy functions and datasets, not help pages. Arni
