使用UTF-8时最差的编码错误 [英] R rvest encoding errors with UTF-8
问题描述
我正在尝试从Wikipedia获取此表.文件的来源是UTF-8:
I'm trying to get this table from Wikipedia. The source of the file clamis it's UTF-8:
> <!DOCTYPE html> <html lang="en" dir="ltr" class="client-nojs"> <head>
> <meta charset="UTF-8"/> <title>List of cities in Colombia - Wikipedia,
> the free encyclopedia</title>
> ...
但是，当我尝试使用rvest来获取表格时，它会在应该加重(标准西班牙文)的á，é等字符的地方显示奇怪的字符.
这是我尝试过的:
However, when I try to get the table with rvest it shows weird characters where there should be accented (standard spanish) ones like á, é, etc.
This is what I attempted:
theurl <- "https://en.wikipedia.org/wiki/List_of_cities_in_Colombia"
file <- read_html(theurl, encoding = "UTF-8")
tables <- html_nodes(file, "table")
pop <- html_table(tables[[2]])
head(pop)
## No. City Population Department
## 1 1 Bogotá 6.840.116 Cundinamarca
## 2 2 MedellÃn 2.214.494 Antioquia
## 3 3 Cali 2.119.908 Valle del Cauca
## 4 4 Barranquilla 1.146.359 Atlántico
## 5 5 Cartagena 892.545 BolÃvar
## 6 6 Cúcuta 587.676 Norte de Santander
如其他SO问题中所建议的，我尝试使用以下方法修复编码:
I have attempted to repair the encoding, as suggested in other SO questions, with:
repair_encoding(pop)
## Best guess: UTF-8 (100% confident)
## Error in stringi::stri_conv(x, from = from) :
## all elements in `str` should be a raw vectors
我已经测试了几种不同的编码(latin1和guess_encoding()提供的其他编码，但是所有编码都会产生类似的错误结果.
I've tested several different encodings (latin1, and others provided by guess_encoding(), but all of them produce similarly incorrect results.
如何正确加载此表?
推荐答案
似乎您必须在字符向量上使用repair_encoding，而不是整个数据帧...
It looks like you have to use repair_encoding on a character vector, not an entire dataframe...
> repair_encoding(head(pop[,2]))
Best guess: UTF-8 (80% confident)
[1] "Bogotá" "Medellín" "Cali" "Barranquilla"
[5] "Cartagena" "Cúcuta"
