xml – readHTMLTable和UTF-8编码

我一般都有read HTMLTable和 XML包的编码问题.我想从波兰网站allegro.pl(类似于ebay的拍卖网站)下载一些表格,但在此之后,波兰字体存在编码问题,即使我使用的是编码=“UTF-8”或stringsAsFactors = F in readHTMLTable.

码：

library(XML)
url<-paste("http://allegro.pl/listing.php/search?category=15821&sg=0&p=",1:5,"&string=facebook",sep="")

alldata<-NULL

for (i in 1:5){
dane<-as.data.frame(readHTMLTable(url[i],1,stringsAsFactors = TRUE,encoding="UTF-8")$lista)
alldata<-rbind(alldata,dane)
}

结果：

> head(alldata[,c(2,3)])
                                                        V2                      V3

如果我使用getURL或readLines没有问题,但我想使用XML包,因为它是伟大的事情:)

当我使用XML包函数(如htmlParse,xpathApply或提到的readHTMLTable)时总会出现这个问题.
