问题 I am working with a CSV file right now. In my program i am using an OutputStreamWriter to write data the csv file. OutputStreamWriter myOutWriter = new OutputStreamWriter(fOut, Charset.forName("UTF-8").newEncoder()); I tried printing out the encoding style of this writer and get the following: Log.i(TAG, "BODY ENCODING: " + myOutWriter.getEncoding()); Logcat: BODY ENCODING: UTF-8 But when i try to open the csv file on my desktop it says that the file is in windows-1252 so i cant read æøå

问题 I'm trying to extract the special characters (out of a predefined pattern) from a string, but when that string begins with an inverted question mark, "matches" returns first two characters, including a not special one. Eg.: $string = '¿hola?'; $string2 = mb_convert_encoding($string, 'UTF-8'); $regex = mb_convert_encoding('/[a-zäáàëéèíìöóòúùñç]/', 'UTF-8'); if(preg_match($regex, $string2, $matches, PREG_OFFSET_CAPTURE)) { //--> We pick the special characters into "$resultado1": $resultado1 =

问题 With POST is easy and automatic: just use application/x-www-form-urlencoded or multipart/form-data or whatever. Instead, what parts should be encoded in a GET request? The whole query string? Just the parameter values but not the names ? And the fragment ? Maybe also the path ? But am pretty sure that I shouldn't encode the host or the scheme (since there are encoding and specs for international domains, like in japanese etc.). Hence the question is more about the URI 😉 Strangely I didn't

问题 I try to export a CSV file with JasperReport, the problem is when I want to print currency like '€'. When I search for solution, I realized that it's about file encoding!

问题 I am encrypting an NSString in iOS like this which encodes and decodes fine: NSString *stringtoEncrypt = @"This string is to be encrypted"; NSString *key = @"12345678901234567890123456789012"; // Encode NSData *plain = [stringtoEncrypt dataUsingEncoding:NSUTF8StringEncoding]; NSData *cipher = [plain AES256EncryptWithKey:key]; NSString *cipherBase64 = [cipher base64EncodedString]; NSLog(@"ciphered base64: %@", cipherBase64); // Decode NSData *decipheredData = [cipherBase64 base64DecodedData];

I am using this code: FrameGrabber grabber = new FFmpegFrameGrabber(inputFile.getAbsolutePath()); grabber.start(); FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(outputFile.getAbsolutePath(), grabber.getImageWidth(), grabber.getImageHeight(), grabber.getAudioChannels()); recorder.setVideoCodec(com.googlecode.javacv.cpp.avcodec.AV_CODEC_ID_MPEG4); recorder.setAudioCodec(com.googlecode.javacv

问题 I am using the following code to render my webview in android - webview.loadDataWithBaseURL(null, "Subject: "+ getSubject() +" Content: "+ getContent() , "text/html" , "UTF-8", ""); The subject and content that I receive from the server are UTF encoded and show wrongly as Ã¥,ä,ö in the log and on screen.
