encoding

问题 I am trying to get a byte array from an NSString in objective c using ascii encoding. I need to this array to calculate the SHA256 hash of that string and then compare the result to the SHA256 encoding generated in Windows. NSString *myString = @"123456¥"; const char *string = (const unsigned char *) [myString cStringUsingEncoding:NSASCIIStringEncodin]; this always gives nil since it contains the ¥ character. the problem is I cannot use UTF8Encoding since the hash generated by windows uses

问题 I am new to SSIS, I have already designed a package and configured SSIS Log provider for Text Files. This works fine and log files are generated successfully. We have a monitoring team, they use this log file for monitoring. They are unable to read the log files since the file encoding is in Unicode format. They are expecting a non unicode format for their monitoring. I tried to change the existing log file encoding to ANSI but when I re-run the package my log file has been created again with

问题 I have a column of a dataframe that is like this time 0 2017-03-01 15:30:00 1 2017-03-01 16:00:00 2 2017-03-01 16:30:00 3 2017-03-01 17:00:00 4 2017-03-01 17:30:00 5 2017-03-01 18:00:00 6 2017-03-01 18:30:00 7 2017-03-01 19:00:00 8 2017-03-01 19:30:00 9 2017-03-01 20:00:00 10 2017-03-01 20:30:00 11 2017-03-01 21:00:00 12 2017-03-01 21:30:00 13 2017-03-01 22:00:00 . . . I want to "encode" the time of the day. I want to do this by firsly assigning each half an-hour a integer number. Starting

问题 I've been searching for this one and couldn't find it, although it seems simple. I need to send in a ucs2 hex string in the url, and I don't know how to convert a python string to be ucs2 hex. Any thoughts? 回答1: >>> 'åéîøü'.encode('utf16') b'\xff\xfe\xe5\x00\xe9\x00\xee\x00\xf8\x00\xfc\x00' (Note that there's a BOM in the beginning. Use the encoding 'utf_16_be' or 'utf_16_le' if the endian is fixed.) If you need hex digits, use binascii.hexlify. >>> import binascii >>> binascii.hexlify('åéîøü

问题 I am having trouble displaying Russian characters in the Rstudio console. I load an Excel file with Russian using the readxl package. The cyrillic displays properly in the dataframe. However, if I run a function that has an output that includes the variable names, the RStudio consoles displays symbols instead of the proper Cyrillic characters. test.xlsx contains two columns - зависимая переменная (dependent variable - numeric) and независимая переменная (independent variable, factor).

问题 I created a corpus in R using package tm specifying language and encoding as follows: de_DE.corpus <- Corpus(VectorSource(de_DE.sample), readerControl = list(language="de_DE",encoding = "UTF_8")) de_DE.corpus[36]$content de_DE.dtm <- DocumentTermMatrix(de_DE.corpus,control = list (encoding = 'UTF-8')) inspect(de_DE.dtm[, grepl("grÃ", de_DE.dtm$dimnames$Terms)]) inspect(de_DE.dtm[36, ]) If I see the content in de_DE.corpus[36]$content of document 36 which has 'ü' the text is shown correctly. e

问题 I've to merge two (or more) audio files (like a guitar and a drum track) into a single file. I'm running over linux CentOS and I'd need a command line tool to do so, because I've got to run this as part of a background process, triggered via crontab of a custom bash script. I also need to be able to change the pan, volume, trim and start time (i.e I want the guitar track to start after 1.25ms after the drum track so that they can be both in sync with each other). My first choice would be

问题 My Jekyll installation used to work. Since an update, I face an issue with URL containing tag names which have some special characters. I now get an error message when trying to reach a URL with special characters in it like http://127.0.0.1:4000/tag/Actualit%C3%A9%20europ%C3%A9enne/ , where Actualité européenne is the name of a category. The error message is incompatible character encodings: UTF-8 and ASCII-8BIT . All the files in _posts directory are utf-8. Here is the stack trace : [2017
