如何在R的书形标题中使用UTF-8字符 [英] How to use UTF-8 characters in dygraph title in R

问题描述

使用Rstudio [Windows8]，当我使用dygraph函数绘制时间序列时，尝试在主标题中使用UTF-8字符时遇到问题.

Using Rstudio [Windows8], when I use the dygraph function to plot a time series, I have a problem when trying to use UTF-8 characters in the main title.

library(dygraphs)
dygraph(AirPassengers, main = "Título")

这将产生一个标题:"T?tulo"

This results in a title: "T?tulo"

我尝试将Título"转换为utf-8编码，但不起作用.

I have tried to convert "Título" to the utf-8 enconding, but it doesn't work.

推荐答案

您需要确保您的语言环境设置支持您要使用的字符，并且文件已使用正确的编码保存.另存为UTF-8对我有用.

You need to make sure your locale settings support the character that you want to use, and that the file is saved with the right encoding. Saving as UTF-8 worked for me.

我能够在Windows 7中复制您的情况，并尝试了很多方法.嵌入在Rmarkdown中，这是一个最小的工作示例.

I was able to replicate your situation in Windows 7 and tried a bunch of things. Embedded in Rmarkdown, here is a minimal working example.

```{r}
Sys.setlocale("LC_ALL","German")
#note that windows locale names are different from unix & mac, usually
#the name of nationality works here.
#also works with "Faroese", "Hungarian", and others who have this letter.
#the locale has to be set in a preceding block to take effect.
```

```{r}
Encoding("Título")
library(dygraphs)
dygraph(AirPassengers, main = "Título")
```

您可以尝试使用Encoding()赋予标题的编码.诸如法罗语，匈牙利语和德语之类的语言将Título"编码为拉丁语或未知语，这两种语言对于dygraph的javascript似乎都不会造成问题. UTF-8将其写为<U+00ED>，这对于javascript以及某些但不是所有其他功能来说都是一个问题.在具有匹配的语言环境的情况下，按照@Michele的建议转换为utf-8的结果相同.

You can try out the encoding given to the title to have with Encoding(). Languages like Faroese, Hungarian, and German encode "Título" as latin or unknown, both of which seem to cause no problems for dygraph's javascript. UTF-8 wrote it as <U+00ED> which was a problem for the javascript, as well as some, but not all other functions. With a matching locale, converting to utf-8 as @Michele recommended has the same result.

此外，如果您在很多地方都没有标题，则可以在创建的html/javascript文件中手动查找和替换标题.转换时会出现问题，但是如果已经制作了文件，则可以成功更改title变量.该字母在Rstudio查看器"输出中仍然带有问号，但是我建议定期制作整个javascript文件，因为我已经在查看器窗口中看到其他功能出现了问题.

Also, if you don't have the title in many places, it is possible to just manually find and replace the title in the html/javascript file that is made. The problem occurs on conversion, but if the file is already made, the title variable can be successfully changed. The letter still has a question mark in Rstudio "Viewer" output, but I recommend making the entire file for javascript regularly, as I've seen other functions malfunction in the viewer window.
