encoding

问题 The impetus is: I have some JSON that I've been saving as .txt files for a bit. I'd like to rename them all to .json to be more accurate. I'm pretty sure they are both UTF-8, as are most files that can be sent over Ajax. Anyways, this question raised a bigger question. Is there any real difference between all of these text types, other than the extension? .html, .json, .css, .js, .txt, .py, etc... they all appear to be the same thing on the inside: a UTF-8 character array. If you used these

问题 I have a 37 column CSV file that I am parsing in Java with Apache Commons CSV 1.2. My setup code is as follows: //initialize FileReader object FileReader fileReader = new FileReader(file); //intialize CSVFormat object CSVFormat csvFileFormat = CSVFormat.DEFAULT.withHeader(FILE_HEADER_MAPPING); //initialize CSVParser object CSVParser csvFileParser = new CSVParser(fileReader, csvFileFormat); //Get a list of CSV file records List<CSVRecord> csvRecords = csvFileParser.getRecords(); // process

问题 How can I find extended ASCII characters in a file using Perl? Can anyone get the script? .....thanks in advance..... 回答1: Since the extended ASCII characters have value 128 and higher, you can just call ord on individual characters and handle those with a value >= 128. The following code reads from stdin and prints only the extended ASCII characters: while (<>) { while (/(.)/g) { print($1) if (ord($1) >= 128); } } Alternatively, unpack together with chr will also work. Example: while (<>) {

问题 I want to use the infinity sign on the x-axis of a box plot in R, which I want to write to a PDF file. I can set the infinity symbol by doing names(data)[9] <- "∞" but that gets me encoding errors when trying to write: conversion failure on '∞' in 'mbcsToSbcs': dot substituted for <...> 回答1: You can either use Unicode as in this example: using Unicode 'dingbat-like' glyphs in R graphics, across devices & platforms, especially PDF (infinity is Unicode 8734): in particular, it's possible that

问题 Folks! I am trying to display ® and superscript TM symbols in my silverlight app. I want to save the text containing the symbols in a resx file. Things i have tried: Copy paste the ® symbol from any document to resx file. ® symbol gets displayed in the resx file. But, when running the silverlight app, xamlparseexception is thrown. Use unicode text &#174 instead of ® symbol in the resx file. Same xamlparseexception thrown. My resx file encoding is utf-8. Appreciate your thoughts! EDITED:

问题 According to bin2hex my PHP is internally using UTF-8: echo bin2hex("ö"); -> c3b6 (utf-8) echo bin2hex(utf8_decode("ö")); -> f6 (ISO-8859) But both mb_internal_encoding() and iconv_get_encoding() say it is ISO-8859-1. echo mb_internal_encoding(); -> ISO-8859-1 var_dump(iconv_get_encoding()); -> ["input_encoding"]=> string(10) "ISO-8859-1" ["output_encoding"]=> string(10) "ISO-8859-1" ["internal_encoding"]=> string(10) "ISO-8859-1" UTF-8 seems to apparently be the one it's using, but why is it

问题 I have a string $data, encoded in utf-8. I assume that I don't know whether this string is utf-8 or iso-8859-1. I want to use the Perl Encode::Guess module to see if it's one or the other. I'm having trouble figuring out how this module works. I have tried the four following methods (from http://perldoc.perl.org/Encode/Guess.html) : use Encode::Guess qw/utf8 latin1/; my $decoder = guess_encoding($data); print "$decoder\n"; Result: iso-8859-1 or utf8 use Encode::Guess qw/utf8 latin1/; my $enc

问题 I get the following error when I send form data to my Flask app. It says it will use the UTF-8 encoding, but the locale is already UTF-8. What does this error mean? /home/.virtualenvs/project/local/lib/python2.7/site-packages/werkzeug/filesystem.py:63: BrokenFilesystemWarning: Detected a misconfigured UNIX filesystem: Will use UTF-8 as filesystem encoding instead of 'ANSI_X3.4-1968' $ locale LANG=en_US.utf8 LANGUAGE=en_US.utf8 LC_CTYPE="en_US.utf8" LC_NUMERIC="en_US.utf8" LC_TIME="en_US.utf8"
