decode

问题 I have never dealt with encoding and decoding strings, so I am quite the newbie on this front. I am receiving a UnicodeEncodeError when I try to write the contents I read from another file to a temporary file using file.write in Python. I get the following error: UnicodeEncodeError: 'ascii' codec can't encode character u'\u201c' in position 41333: ordinal not in range(128) Here is what I am doing in my code. I am reading an XML file and getting the text from the "mydata" tag. I then iterate

问题 Itroduction I'm currently working on John Conway's Game of Life in js. I have the game working (view here) and i'm working on extra functionalities such as sharing your "grid / game" to your friends. To do this i'm extracting the value's of the grid (if the cell is alive or dead) into a long string of 0's and 1's. This string has a variable length since the grid is not always the same size. for example: grid 1 has a length and width of 30 => so the string's length is 900 grid 2 has a length

问题 I am trying to parse base64 type into imageData. But my NSDataBase64DecodingOptions returns nil. I printed decodedData and it is nil. My code is here var base64String = arrayText["auto_type_android_img"] as String println("basestring64 is \(base64String)") let decodedData = NSData(base64EncodedString: base64String, options: NSDataBase64DecodingOptions(rawValue: 0)) println("base string is: \(decodedData)") if let decodedImage = UIImage(data: decodedData!) { imageTypeOfCar?.image =

问题 I have been trying to decode a video file which is encoded via H264 encoding with Android's MediaCodec and tried to put the output of the decoder to a surface , but when I run the app it shows a black surface and in DDMS logcat I see that decoder timed out . I have parsed the file into valid frames first [reading 4 bytes first which indicates the length of the upcoming frame and then read length amount bytes which indicates the frame, then again reading 4 bytes for the length of the next

问题 i have a variable holding a value like x='مصطفى' and i want to convert it to the form of u'مصطفى' to user it again in some functions .. when i try to do u''+x it alawys give me an error: UnicodeDecodeError: 'ascii' codec can't decode byte 0xd9 in position 0: ordinal not in range(128) Any help ? 回答1: You have to know what encoding those bytes are in, and them .decode(encoding) them to get a Unicode string. If you received them from some API, utf8 is a good guess. If you read the bytes from a

问题 I can't seem to decode this base64 string which is in the footer of a wordpress theme. I want to be able to add more to the footer. Any help appreciated, thanks! <?php eval(stripslashes(gzinflate(base64_decode("fZHBasMwDIbvhb6DyGHtLs19zRIoY9tte4BAsRMlNjiWScSyvP0Ur3iFlvliR/ry/+JXVRZ5a7/K7aaQCxqnpum5zhryjJ41MdNQZwm6YLYVpiNiHKW53UA6Dw2F5QiFAjNiJ1RRBRMAG0PQI58psCW/r3eGBqx3j0eoyrzOgC07TLh21FvfkXBeJW6d4592kasSXnCyvccW9HI1hGEOT3nejYi9/DAdhu8rz1cpw9taF4e/j6hnPTTknNI0qnVymC2bW2U9kHfWX9SbNbMk/

问题 Is there a way that I can exclude particular string (II*) while encode a tiff file and keep that String as it is and also during the decode ? Or How can I specify the encoding to always encode (II*) as three characters and not to combine with any other characters ? Below code to replace the string II* with ( II* ), however tiff got corrupted after that. Path path = Paths.get("D:\\Users\\Vinoth\\workspace\\Testing\\Testing.tiff"); Charset charset = StandardCharsets.UTF_8; String content = new

问题 I want to encode/decode a string in AS3: var string:String = "This is an text"; encode(string) will give for example: yuioUasUenUwdfr . decode(encoded(string)) will give: This is an text . It does not have to be secure or anything. 回答1: I would suggest either base64 or rot13 encoding. There are many AS3 implementations for each. Google will provide. 回答2: Another option is using a XOR cypher, with a key. This method is totally breakable, of course, but it takes a bit more work, so for
