encoding

问题 I'm running a asp.net web application on Azure, I have an Application Gateway in front of it, enable the WAF (Web application Firewall). But many of my http requests from the front-end are blocked by the WAF, for example my payload in JSON: [{"inputtype":"text","name":"wwwwww","memo":"","score":1,"sort":1,"isrequired":false,"allowseeresult":false,"choicenummin":null,"choicenummax":null,"options":[]}] The error message is: "message": "Warning. Pattern match \"((?: [\\\\~\\\\!\\\\@\\\\#\\\\$\\\

问题 I have an App that reads data from a server. Now and then, the data appears to be not valid UTF-8. If I convert from the byte array to an UTF8-String, the string appears nil. There must be some invalid not-UTF8 character in the byte array. Is there a way to 'lossy' convert the byte array to UTF8 and filter out only the invalid characters? Any ideas? My code looks like this: - (void)stream:(NSStream *)theStream handleEvent:(NSStreamEvent)streamEvent { switch (streamEvent){ case

问题 I'm developing an Android application which sends commands to a remote equipment through SMS. The commands are all regular text messages, and some of them start with the prefix A@@ . To test the app I sent some "commands" to other phones using an Android 4.3 phone and also an Android 2.3 phone. When I run the app on the Android 4.3 phone, the SMS on the receiving end shows just fine on any device, but if I use the Android 2.3 to send the commands they get received as A¿¿ on an Android 4.3

问题 I have the following c++ code in visual studio to read characters from a file. ifstream infile; infile.open(argv[1]); if (infile.fail()) { cout << "Error reading from file: " << strerror(errno) << endl; cout << argv[0] << endl; } else { char currentChar; while (infile.get(currentChar)) { cout << currentChar << " " << int(currentChar) << endl; //... do something with currentChar } ofstream outfile("output.txt"); outfile << /* output some text based on currentChar */; } infile.close(); The file

问题 I am developing an application in which i want to encode the Spanish text. But the problem is that,it doesn't encode the special characters such as á, é, í, ó, ú, ü,Á, É, Í, Ó, Ú, Ü,Ñ,ñ . How can i do this?i want to encode-decode the spanish text . 回答1: For international support using simple UTF-8 encoding to encode/decode your data should be enough. Utf-8 has a beautiful capability to be able to read ASCII with one byte, as ordinary ASCII, and Unicode characters with 2 bytes. So it's able

问题 I have a String which contains some encoded values in some way like Base64. The problem is that I really don't know if it's actually Base64 (there are A-Z, a-z. 0-9, +, /) so it can be some any other code that i'm not familiar with. Is there a way or any other online site to send him an encoded input and it can tell me in which code is it? NOTE: I'm not asking how to know if my String is UTF-8 or iso-8859-1 or something like that. What I need is to know in which is my code is encoded. EDIT:

问题 We are experiencing problems with encoding, pattern matching using texts automatically downloaded from the web. We need some help to understand where the problem lies and how to fix it. Personally, I must confess that after having read so many posts on the topic, I am completely confused :-) Our texts sometimes include: 1) disturbing Unicode (I have read this already (Automatically escape unicode characters ), but I am not sure in which way it can help with regular expressions) 2) weird

问题 I've been working with PAR::Packer to create standalone executable files out of Perl scripts. The only difficulty I have with it is figuring out what extra DLLs I have to force it to include via the -l option. I'm now working with a Perl script that requires Encoding with utf16-le. The Encode::find_encoding function works just fine in the script, but it doesn't work after I have packaged it with pp . Here's a tiny script (let's call it encode.pl) to illustrate the problem: use strict; use

问题 g++ does not compile my source files which are in UTF-16 encoding. Is it possible to do it or should I use UTF-8 encoding? 来源： https://stackoverflow.com/questions/19617203/g-compiling-sources-in-utf-16-encoding
