encoding

问题 I am trying to use aws-sdk to load s3 files to local disk, and question why my pdf file (which just has a text saying SAMPLE PDF) turns out with an apparently empty content. I guess it has something to do with the encoding...but how can i fix it? Here is my code : require 'aws-sdk' bucket_name = "****" access_key_id = "***" secret_access_key = "**" s3=AWS::S3.new( access_key_id: access_key_id, secret_access_key: secret_access_key) b = s3.buckets[bucket_name] filen = File.basename("Sample.pdf"

问题 i upgraded from Ruby 1.8.7 to 1.9.2 (and Rails 3.2.2) and have the problem that Net::FTP#gettextfile is throwing an Encoding::UndefinedConversionError I'm trying to download a xml file which is encoded as utf-8. The dowload works fine if i use getbinaryfile, but i would like to understand why gettextfile is not working. # -*- encoding : utf-8 -*- # working ftp = Net::FTP.open(host,user,password) ftp.passive = true ftp.getbinaryfile("some.xml","tmp/some.xml") # not working ftp = Net::FTP.open

问题 When I execute SELECT query in php in order to get data from MySQL DB into bootstrap table, the apostrophes are not displayed correctly in the table rows. In particular, I get Gr�a instead of Grúa . This is how I get data from MySQL DB: <?php include_once 'include/connect_db.php'; $query = "SELECT * FROM myTable;"; $result = ejecutar_query($query); $list = array(); while ($b = mysqli_fetch_array($result)) { $list[] = $b; } ?> <td><?php echo $row['name'];?></td> <!--jQuery Datatable--> <script

问题 I'm currently studying the Abstract Syntax Notation One and reading the ITU-T Recommendation X.690. On page 15 in paragraph 8.3.2, there is written: If the contents octets of an integer value encoding consist of more than one octet, then the bits of the first octet and bit 8 of the second octet: shall not all be ones; and shall not all be zero. NOTE – These rules ensure that an integer value is always encoded in the smallest possible number of octets. I understand that for the integer to be

问题 I am running a Java application on a Solaris10 with Chinese . Now there are some files in a directory with chinese filenames. When I do files = new File(dir).list() where "dir" is the parent directory containing that chinese file, I get the result filename files[0] as ????? (some junk characters). Now the deal is that my programs file.encoding property is already set to GBK and I also do Charset.isSupported("GBK") and it returns true too. So where could be the problem. I am running out of

问题 Python 3 cleans up Python's handling of Unicode strings. I assume as part of this effort, the codecs in Python 3 have become more restrictive, according to the Python 3 documentation compared to the Python 2 documentation. For example, codecs that conceptually convert a bytestream to a different form of bytestream have been removed: base64_codec bz2_codec hex_codec And codecs that conceptually convert Unicode to a different form of Unicode have also been removed (in Python 2 it actually went
