Convert a file encoding using R? (ANSI to UTF-8)

问题

I wish to convert an HTML file encoded in ANSI to UTF-8, using R.

Is there a tool, or a combination of tools, that can make this work?

Thanks.

Edit: o.k, I've narrowed my problem to another one. It is re-posted here: Using "cat" to write non-English characters into a .html file (in R)

回答1:

you can use iconv:

writeLines(iconv(readLines("tmp.html"), from = "ANSI_X3.4-1986", to = "UTF8"), "tmp2.html")

tmp2.html should be utf-8.

A working solution for Windows distilled from the comments is as follows:

writeLines(iconv(readLines("tmp.html"), from = "ANSI_X3.4-1986", to = "UTF8"), 
           file("tmp2.html", encoding="UTF-8"))

I had some problems with the solutions proposed above, especially with the TAB character. This alternative never disappointed me. Unfortunately it only works on UNIX-like systems.

system('iconv -f CP1252 -t UTF-8 < tmp.html > tmp2.html')
