I have used the Apache Commons StringEscapeUtils.unescapeHtml4() for this: Unescapes a string containing entity escapes to a string containing the actual Unicode characters corresponding to the escapes. Supports HTML 4.0 entities.
What about org.apache.commons.lang.StringEscapeUtils’s unescapeHtml(). The library is available on Apache site. (EDIT: June 2019 – See the comments below for updates about the library)

i have solved this issue. we can use this code import codecs types_of_encoding = [“utf8”, “cp1252″] for encoding_type in types_of_encoding: with codecs.open(filename, encoding = encoding_type, errors=”replace”) as csvfile: your code …. ….
Assuming the image data is already in the format you want, you don’t need ImageIO at all – you just need to write the data to the file: // Note preferred way of declaring an array variable byte[] data = Base64.decodeBase64(crntImage); try (OutputStream stream = new FileOutputStream(“c:/decode/abc.bmp”)) { stream.write(data); } (I’m assuming you’re using Java … Read more
Many filetypes have a header (the first few bytes of the file) with some fixed information by which a file can be identified as a gz, png, pdf, etc. So every base64 encoded gz file would also start with a certain sequence of base64 characters, by which it can be recognized. A gzip-file always starts … Read more
You will need to import dart:convert: import ‘dart:convert’; Inline example String rawJson = ‘{“name”:”Mary”,”age”:30}’; Map<String, dynamic> map = jsonDecode(rawJson); // import ‘dart:convert’; String name = map[‘name’]; int age = map[‘age’]; Person person = Person(name, age); Note: When I was doing this in VS Code for server side Dart I had to specify the type: Map<String, … Read more
You have to cast your dictionary value from AnyObject to String. You have also to decode your string data using .IgnoreUnknownCharacters option. Try like this if let encodedImage = json[“image”] as? String, imageData = NSData(base64EncodedString: encodedImage, options: .IgnoreUnknownCharacters), image = UIImage(data: imageData) { print(image.size) } Swift 3.0.1 • Xcode 8.1 if if let encodedImage = … Read more
Python is trying to be helpful. You cannot decode Unicode data, it is already decoded. So Python first will encode the data (using the ASCII codec) to get bytes to decode. It is this implicit encoding that fails. If you have Unicode data, it only makes sense to encode to UTF-8, not decode: >>> print … Read more
There are many similar questions and useful answers in stackoverflow but I can’t find a way works both on browsers and Node.js. So I’d like to share my opinion. For html codes like < > ' and even Chinese characters. I suggest to use this function. (Inspired by some other answers) function decodeEntities(encodedString) { … Read more
