Getting htmlParse to work with Hebrew?

问题

I wish to be able to have htmlParse work well with Hebrew, but it keeps to scramble the Hebrew text in pages I feed into it.

For example:

# why can't I parse the Hebrew correctly?
library(RCurl)
library(XML)
u = "http://humus101.com/?p=2737"
a = getURL(u) 
a # Here - the hebrew is fine.
a2 <- htmlParse(a)
a2 # Here it is a mess...

None of these seem to fix it:

htmlParse(a, encoding = "utf-8")
htmlParse(a, encoding = "iso8859-8")

This is my locale:

> Sys.getlocale()
[1] "LC_COLLATE=Hebrew_Israel.1255;LC_CTYPE=Hebrew_Israel.1255;LC_MONETARY=Hebrew_Israel.1255;LC_NUMERIC=C;LC_TIME=Hebrew_Israel.1255"
>

Any suggestions?

Specify UTF-8 endoding in both the call to getURL and htmlParse.

a <- getURL(u, .encoding = "UTF-8")
htmlParse(a, encoding = "UTF-8")

These locale issues are always a pain to get to the bottom of. When I type cat(a) (after specifying UTF-8 encoding in getURL) I see that the he.wrodpress.org page claims to be UTF-8: <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />, but the Hebrew bits are UTF-16. That is, they look like <U+05D3><U+05E6><U+05DE><U+05D1><U+05E8>. So it could be a problem caused by mixed oncoding of that web page.

Comparing several encodings, the only one that doswn't generate gibberish on my machine is UTF-8.

(trees <- lapply(c("UTF-8", "UTF-16", "latin1"), function(enc)
{
  a <- getURL(u, .opts = proxy_opts, .encoding = enc)
  htmlParse(a, encoding = enc)
}))

If it gets desperate, pass iconvlist() to lapply in the above code, and see if any of the possible condings works for you.
