character-encoding

问题 I am having a csv file which has some fields having chinese character strings. Unfortunately i dont know what is encoding of this input csv file. I am trying to read this input csv and using selective fields from it, i am making a html and another csv file as output. While reading csv input, i tried all encoding from list http://docs.oracle.com/javase/7/docs/technotes/guides/intl/encoding.doc.html which have Chinese mentioned in their description. And found if I use InputStreamReader read =

问题 I'm doing a small client/server project as a final project in a C++ course. We are handed some classes that take care of communication (using sys/socket.h) and we can basically do connection->send(byte) to send one byte of data. Say I have a string that I want to send. How do I make sure an 'a' is interpreted as an 'a' when sent from client to server or vice versa? Since the standard isn't saying anything about char defaulting to unsigned or signed I don't know how to handle it. I had some

问题 This question already has an answer here : PHP and C++ for UTF-8 code unit in reverse order in Chinese character (1 answer) Closed 6 years ago . This is the scenario: I can only use the char* data type for the string, not wchar_t * My MS Visual C++ compiler has to be set to MBCS, not UNICODE because the third party source code that I have is using MBCS; Setting it to UNICODE will cause data type issues. I am trying to print chinese characters on a printer which needs to get a character string

问题 I want to obfuscate a Python script by using Unicode escape sequences. For example, print("Hello World") in Unicode escape sequences is: \x70\x72\x69\x6e\x74\x28\x22\x48\x65\x6c\x6c\x6f\x20\x57\x6f\x72\x6c\x64\x22\x29 From my command line, I can achieve this with: $ python3 -c \x70\x72\x69\x6e\x74\x28\x22\x48\x65\x6c\x6c\x6f\x20\x57\x6f\x72\x6c\x64\x22\x29 Hello World I've create a file and put the "Hello World" Unicode escape sequence in it as the source code. But when I run it, I get: $

问题 I'm using (occasionaly) emacs24.3 on windows 8 and I have a problem of encoding when pasting text , non ascii characters being replaced by their \uucode . My emacs coding default are utf-8 I tried to have a quick look in the apropos help, but nothing matched the keywords i used. What would be the variable to configure, and the value of system encoding for a windows os? 回答1: After some digging, and orientation from lawlist link I went for (set-clipboard-coding-system 'utf-16le-dos) 来源： https:/

问题 I am getting all supported charsets by using : Object[] Charsets = Charset.availableCharsets().keySet().toArray(); I now need to iterate through each character that can be encoded in that charset. To do this I thought about using the maximum number of bytes for each encoding and going through Byte.MIN_VALUE to Byte.MAX_VALUE for each byte. That byte array I then pass it through the String constructor that accepts a byte[] array and a specific encoding. However can't find any clues on how I

问题 I am trying to find data that has accented characters. I've tried this: select * from xml_tmp where regexp_like (XMLTYpe.getClobVal(xml_tmp.xml_data), unistr('\0090')) And it works. It finds all records where the XML data field contains É. The problem is that it only matches the upper-case E with an accent. I tried to write a more generic query to find ALL data with accented vowels (a, e, i, o, u, upper and lowercase, with any accents) using equivalence classes. I wanted a regex to match only

问题 After many tries I have concluded that the optimal way to transfer with SSIS data from AS400 (non-unicode) to SQL Server is: Use native transfer utility to dump data to tsv (tab delimited) Convert files from utf-8 to unicode Use bulk insert to put them into SQL Server In #2 step I have found a ready made code that does this: string from = @"\\appsrv02\c$\bg_f0101.tsv"; string to = @"\\appsrv02\c$\bg_f0101.txt"; using (StreamReader reader = new StreamReader(from, Encoding.UTF8, false, 1000000)
