character-encoding

问题 My understanding is that the ASCII characters found in the range from 0x00 to 0x1f were included with Teletype machines in mind. In the modern era, many of them have become obsolete. I was curious as to which characters might still be found in a conventional string or file. From my experience programming in C, I thought those might be NUL, LF, TAB, and maybe EOT. I'm especially curious about BS and ESC, as I thought (similar to shift or control maybe) that those might be handled by the OS and

问题 I am facing a problem with jetty character encoding. When installed the jetty server on Mac (OSX), it works fine. But, when it is installed on Ubuntu (10.10), the character encoding is not proper. The word in the page (not URL) having problem is: The New York Times® Bestsellers It is shown as "The New York Times� Bestsellers" on the page served by the server on Linux and it is shown as "The New York Times® Bestsellers" on the page served by the server on Mac (This is correct) The jetty

问题 This has been a longstanding problem with R: it can read non-latin characters on Unix, but I cannot read them on Windows . I've reproduced this program on several English-edition Windows machines over the years. I've tried changing the localisation settings in Windows and numerous other to no effect. Has anyone actually been able to read a foreign text file on Windows? I think being able to read/write/display unicode is a pretty nifty feature for a program. Environment: > Sys.getlocale() [1]

问题 I have the following program that reads a file word by word and writes the word again to another file but without the non-ascii characters from the first file. import unicodedata import codecs infile = codecs.open('d.txt','r',encoding='utf-8',errors='ignore') outfile = codecs.open('d_parsed.txt','w',encoding='utf-8',errors='ignore') for line in infile.readlines(): for word in line.split(): outfile.write(word+" ") outfile.write("\n") infile.close() outfile.close() The only problem that I am

问题 I am trying to put Vietnamese labeling in R graphs. I use RStudio and save my code using UTF-8 encoding. It handles the Vietnamese characters I put in the code well, I mean everything shows up in the code properly. However, in the graphs I make, while many characters display OK, several important ones do not show up properly, including đ - which displays incorrectly as d ư - which displays incorrectly as u ơ - which displays incorrectly as o ă - which displays incorrectly as a Unfortunately

问题 I am writing a parser. I have taken care of all the encoding conversion to output UTF-8 correctly, but sometimes the source material is incorrect. such as ☐ or â€tm - the results of bad encoding conversion. I know this is a long shot - but does anyone know of a list of common strings resulting from bad character conversions, or anything so I don't have to build my own list. Yes I know I am being lazy, but I read somewhere that makes me a good programmer? 回答1: tl;dr: See last two paragraphs. I

问题 When I tryed to decode the string below in nodeJS using decodeURLCompnent: var decoded = decodeURI('Ulysses%20Guimar%C3%A3es%20-%20lado%20par'); console.log(decoded); I got Ulysses Guimarães - lado par Instead of Avenida Ulysses Guimarães - lado par But when I use the same code on the client side (browser) I can get the right char 'ã'. Is there a way to convert from ã to ã in a Node script? 回答1: I cannot reproduce it in 0.10 or 0.11 versions of node. You can convert first to second using

问题 This question already has answers here : How to determine the encoding of text? (9 answers) Closed 2 years ago . This is somehow related to my question here. I process tons of texts (in HTML and XML mainly) fetched via HTTP. I'm looking for a library in python that can do smart encoding detection based on different strategies and convert texts to unicode using best possible character encoding guess. I found that chardet does auto-detection extremely well. However auto-detecting everything is
