decoding

问题 So I'm stumped. I know there's lots of Base64 encoders/decoders for JS, but not for the modified (and Facebook-favored) Base64URL variation. So far searching across stackoverflow has come up dry. Yes, I could use PHP or another server-side library to decode this, but I'm trying to keep this universal regardless of what platform I'm using... for example, if I were to host a HTML-only Facebook app on Amazon S3/CloudFront and only use their JS SDK and jQuery to take care of processing forms and

问题 I am fetching posts from the Tumblr API and am running into an encoding issue with the returned "body" of the "post". All apostrophes are replaced by something that looks like "aETM". I am trying to use: utf8_decode($string) But all that does is replace the occurrences of "aETM" with a "?". Any suggestions? 回答1: try $string = mb_convert_encoding($string,'HTML-ENTITIES','utf-8'); 回答2: Use this link to convert string iconv("UTF-8", "CP1252", $data) 来源： https://stackoverflow.com/questions

问题 I have given a Qt Project which needs to support Persian language.T he data is sent from a server and using the first line, I get a QByteArray and convert it to QString using the second line: QByteArray readData = socket->readAll(); QString DataAsString = QTextCodec::codecForUtfText(readData)->toUnicode(readData); When the data is sent is English, everything is fine, but when it is Persian, instead of سلام I get سÙ\u0084اÙ\u0085 I mentioned the process so people wouldn't suggest methods to

问题 I'm trying to convert ascii characters to utf-8. This little example below still returns ascii characters: chunk = chunk.decode('ISO-8859-1').encode('UTF-8') print chardet.detect(chunk[0:2000]) It returns: {'confidence': 1.0, 'encoding': 'ascii'} How come? 回答1: Quoting from Python's documentation: UTF-8 has several convenient properties: It can handle any Unicode code point. A Unicode string is turned into a string of bytes containing no embedded zero bytes. This avoids byte-ordering issues,

问题 I'm trying to write a scrapper, but I'm having issues with encoding. When I tried to copy the string I was looking for into my text file, python2.7 told me it didn't recognize the encoding, despite no special characters. Don't know if that's useful info. My code looks like this: from urllib import FancyURLopener import os class MyOpener(FancyURLopener): #spoofs a real browser on Window version = 'Mozilla/5.0 (Windows; U; Windows NT 5.1; it; rv:1.8.1.11) Gecko/20071127 Firefox/2.0.0.11' print

问题 I have detected that function avcodec_decode_audio3 works slow with mp4 format, here my code cycle for decoding audio: while (av_read_frame(av_format_context, &packet) >= 0 && is_play == 1) { if (av_codec_context->codec_type == AVMEDIA_TYPE_AUDIO && is_play == 1) { int out_size = AVCODEC_MAX_AUDIO_FRAME_SIZE; int size = packet.size; int n; int dataLength = size; int decoded = 0; while (size > 0) { //start measure time gettimeofday(&tvBegin, NULL); int len = avcodec_decode_audio3(av_codec

问题 It is really confusing to handle non-ascii code char in python. Can any one explain? I'm trying to read a plain text file and replace all non-alphabetic characters with spaces. I have a list of characters: ignorelist = ('!', '-', '_', '(', ')', ',', '.', ':', ';', '"', '\'', '?', '#', '@', '$', '^', '&', '*', '+', '=', '{', '}', '[', ']', '\\', '|', '<', '>', '/', u'—') for each token i got, i replace any char in that token with space by calling for punc in ignorelist: token = token.replace
