问题 I have a webpage that accepts CSV files. These files may be created in a variety of places. (I think) there is no way to specify the encoding in a CSV file - so I can not reliably treat all of them as utf-8 or any other encoding. Is there a way to intelligently guess the encoding of the CSV I am getting? I am working with Python, but willing to work with language agnostic methods too. 回答1: There is no correct way to determine the encoding of a file by looking at only the file itself, but you

问题 using System; namespace UnicodeRlm { class Program { static void Main(string[] args) { var uri = new Uri( "https://example.com/attachments/The title is \"مفتاح معايير الويب!‏\" in Arabic.pdf"); Console.WriteLine(uri.AbsolutePath); Console.WriteLine(uri.AbsolutePath.Length); } } } Under .NET 4.0, this produces /attachments/The%20title%20is%20%22%D9%85%D9%81%D8%AA%D8%A7%D8%AD%20%D9%85%D8%B9%D8%A7%D9%8A%D9%8A%D8%B1%20%D8%A7%D9%84%D9%88%D9%8A%D8%A8!%E2%80%8F%22%20in%20Arabic.pdf 168 Under .NET 4

问题 I want to print n Greek characters in Java starting from alpha (whitch has the "\u03B1" code).This is what I had in mind: String T = ""; for(int i = 0,aux = 0;i<n;i++) { aux = '\u03B1' + i; T +=Character.toString((char)aux); } System.out.println(T); But it prints n question marks instead. Let's say n=3,on the output i get "???". I thought that maybe my method is wrong but then again if I try something like this: System.out.println("\u03B1\u03B2\u03B3"); I get the same output:"???" Why do I

问题 I have the following problem I am using an SDK that returns values form a database. The value i need is 4, 6, 7 but the SDK returns "\u0004","\u0006","\u0007" I was wondering if there is a way to check if it is "\u0004","\u0006","\u0007" or any way of doing this? I Have the following code (C#): Line_Type = Line_Type.Replace(@"\u000", ""); if (Line_Type == "4") { Line_Type = "4"; } else if (Line_Type == "6") { Line_Type = "6"; } else if (Line_Type == "7") { Line_Type = "7"; } I have tried

问题 I'm running Joomla 2.5 on an IIS7 server. The problem is Joomla's search engine friendly urls don't work. Whatever url I enter, it goes to index.php. After a painful day of struggling with rewrite rules and IIS settings, I came to two realizations: Search engine friendly urls are only broken when the urls are unicode. In my WAMP server, on which the SEF urls work perfectly: $_SERVER['REQUEST_URI'] is "mydomain/%D9%85%D8%AD%D8%B5%D9%88%D9%84%D8%A7%D8%AA/%D9%82%D9%84%D8%A8%DB%8C-%D8%B9%D8%B1%D9

问题 I am trying to use the encode method of python strings to return the unicode escape codes for characters, like this: >>> print( 'ф'.encode('unicode_escape').decode('utf8') ) \u0444 This works fine with non-ascii characters, but for ascii characters, it just returns the ascii characters themselves: >>> print( 'f'.encode('unicode_escape').decode('utf8') ) f The desired output would be \u0066 . This script is for pedagogical purposes. How can I get the unicode hex codes for ALL characters? 回答1:
