问题 I get some HTML code like the following: <new>8003,%u767E%u5723%u5E97,113734,%u4E50%u4E8B%u542E%u6307%u7EA2%u70E7%u8089%u5473,6924743915824,%u7F50,104g,3,21.57,-2.16,0,%u4E50%u4E8B,1</new> I know I can find and replace all the "%u" with "/u" in Notepad++, and then paste it into Python console to let it display correctly in Chinese characters. But how can I do it automatically in Python? 回答1: Assuming that your input string contains "percent-u" encoded chracters, we can find and decode them

问题 I know that the escape function has been deprecated and that you should use encodeURI or encodeURIComponent instead.

Here are a comparison between escape, encodeURIComponent and encodeURI: console.log("mailto:?subject="+escape(subject)+"&body=" + escape(body)); console.log("mailto:?subject="+encodeURIComponent(subject)+"&body=" + encodeURIComponent

问题 How can I convert string to utf8 byte array, I have this sample code: This works ok: StreamWriter file = new StreamWriter(file1, false, Encoding.UTF8); file.WriteLine(utf8string); file.Close(); This works wrong, file is in ASCII: byte[] bytes = System.Text.UTF8Encoding.UTF8.GetBytes(utf8string); FileStream fs = new FileStream(file2, FileMode.CreateNew); fs.Write(bytes, 0, bytes.Length); fs.Close(); I would like to get byte array what returned by this function: System.IO.File.ReadAllBytes(path

问题 Question Are the Java 8 java.util.Base64 MIME Encoder and Decoder a drop-in replacement for the unsupported, internal Java API sun.misc.BASE64Encoder and sun.misc.BASE64Decoder ?

This RFC is part of the MIME specification... java.util.Base64 based on its JavaDoc Uses
