To ensure consistent behavior across all platforms Mac, Windows, and Linuxyou should set this option explicitly. To fix it, you just have to follow those backwards steps, জোর করে চà§à¦¦à¦²à§‹ বাংলা à¦à¦¿à¦¡à¦¿à¦“.
The special code 0x00 often denotes the end of the input, and R does not allow this value in character strings. Especially if that data came from the people visiting your site.

Unfortunately, you probably found this problem because a bunch of files or database records had badly encoded data in it.
The smallest unit of data transfer on modern computers is the byte, a sequence of eight ones and zeros that can encode a number between 0 and hexadecimal 0x00 and 0xff, জোর করে চà§à¦¦à¦²à§‹ বাংলা à¦à¦¿à¦¡à¦¿à¦“. The last time I fixed this kind of bug, though, I wanted to play it safe.
In practice this জোর করে চà§à¦¦à¦²à§‹ বাংলা à¦à¦¿à¦¡à¦¿à¦“ by first choosing an encoding for the text that assigns each character a numerical value, and then translating the sequence of characters in the text to the corresponding sequence of numbers specified by the encoding.
We will download the text, then read in the lines of the novel.
Whenever you read a text file into R, you need to specify the encoding. We might wonder if there are other lines with invalid data. Not every character can be represented in a single byte, because there are more than possible characters. Given the context of the byte:.
We can see these characters below. So, we should be in good shape.
You could create a giant table, so you could find bad characters and replace them with good ones:. The Latin-1 encoding extends ASCII to Latin languages by assigning the numbers to hexadecimal 0x80 জোর করে চà§à¦¦à¦²à§‹ বাংলা à¦à¦¿à¦¡à¦¿à¦“ 0xff to other common characters in Latin languages. In general, you should determine the appropriate encoding value by looking at the file.
Like I said last week, keeping different interpretations of the same data straight in your head is hard!

There are some other differences between the function which we will highlight below. Joel Spolsky gives a good overview of the situation in an essay from The software community has mostly moved to UTF-8 as a standard for text storage and interchange, জোর করে চà§à¦¦à¦²à§‹ বাংলা à¦à¦¿à¦¡à¦¿à¦“, but there is still a large volume of text in other encodings.
However, if we read the first few lines of the file, we see the following:. The iconvlist function will list the ones that R knows how to process:.
How to Get From They’re to They’re
Practicing complicated ideas like these is the fastest way to feel confident when you need them. And not every file or record is necessarily badly encoded — you might have a mix of good and bad data.
That seems like more than a coincidence, right? Here are the characters corresponding to these codes:. Use encode to convert the UTF-8 string back into a Windows string. Base R format control codes below using octal escapes.
It should just work! Instead, each byte is showing up as a different character. Whenever I found a badly encoded string, I printed it out, along with its replacement:, জোর করে চà§à¦¦à¦²à§‹ বাংলা à¦à¦¿à¦¡à¦¿à¦“.

Last weekyou learned that an encoding is just a way to turn groups of meaningless bytes into displayable characters. Note, however, that this is not the only possibility, and there are many other encodings, জোর করে চà§à¦¦à¦²à§‹ বাংলা à¦à¦¿à¦¡à¦¿à¦“. So try it out! This is a reasonable default, but it is not always appropriate. Note that 0xa3the invalid byte from Mansfield Parkcorresponds to a pound sign in the Latin-1 encoding.

Unfortunately, the file extension জোর করে চà§à¦¦à¦²à§‹ বাংলা à¦à¦¿à¦¡à¦¿à¦“. I used another useful tool to help: my eyes. Before we can analyze a text in R, we first need to get its digital representation, a sequence of ones and zeros.
The others are characters common in Latin languages. To understand why this is invalid, we need to learn more about UTF-8 encoding.
The data is supposed to be UTF-8, but is being misread as Windows Your string has been badly-encoded twice. In the earliest character encodings, the numbers from 0 to hexadecimal 0x00 to 0x7f were standardized in an encoding known as ASCII, the American Standard Code for Information Interchange.
