unicode

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:

问题 I am trying to export data containing Unicode characters from our system using Spreadsheet Gear to csv format. (Fine for excel). However because the CSV format is not UTF-8 encoded all the Unicode characters are exported as ??? I am aware that Spreadsheet Gear supports Unicode by having a tab-delimited UTF-8 text file, however we require the comma-delimited file. This is what currently exists (including my check that the Unicode Text file format exports the characters correctly): public

问题 According to MSDN the minimum value of char is U+0000 and maximum value of char is U+ffff I have written the following code to print the same: using System; using System.Collections.Generic; using System.Linq; namespace myApp { class Program { static void Main() { char min = char.MinValue; char max = char.MaxValue; Console.WriteLine($"The range of char is {min} to {max}"); } } } But I am not getting the output in the format U+0000 and U+ffff. How to get it? 回答1: Your problem is that char when

问题 I have to following string which i get from share point : \u002fsites\u002fblabla\u002fShared Documents\u002fkittens.xml and i'm trying to convert it to : /sites/blabla/Shared Documents/kittens.xml I googled it and found that it is Unicode encoded, but i couldn't find anything that converts it, technically i can write a small function that converts all the "\u002f" to "/" but i don't think it is the right thing to do. If any one can shed some light on this matter it would be very helpful.

问题 I am going to display Unicode dynamically, For example, I know "\U00020001" will display a character. (variable "standard_format" below). However, I can only show the whole string directly ( "\U00020001" ). I would like to know how can I show that string into a character. 回答1: If you write "\U0002B695" the whole string will be recognized as an escape sequence. In "\\U0002B695" however only \\ will be recognized as an escape sequence for \ . I don't know a way to build a string literal this

问题 The following code won't work: using System; using System.IO; using System.Net; using System.Web; namespace Proyecto_Prueba_04 { class Program { /// <summary> /// /// </summary> /// <param name="url"></param> /// <returns></returns> public static string GetWebText(string url) { HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url); request.UserAgent = "A .NET Web Crawler"; WebResponse response = request.GetResponse(); Stream stream = response.GetResponseStream(); StreamReader

问题 I have a Text object that contains some number of Latin characters that needs to be converted to a unicode escape sequence of the format \u#### with # being hex digits As described here, haskell easily converts strings to escape sequences and vice versa. However, it will only go to the decimal representation. For example, > let s = "Ñ" > s "\209" Is there a way to specify the escape sequence encoding to force it to spit out in the correct format? i.e > let s = encodeUnicode16 "Ñ" > s "\u00d1"

问题 I am trying to parse a message that possibly contains emojis in it. An example message that could be received looks like: {"type":"chat","msg":"UserName:\u00a0\ud83d\ude0b \n"} What should match is \u00a0 as a single character, and \ud83d\ude0b as a pair. I have regex that can pull individual codes, but not pairs to match the full emoji: \\u[a-z0-9]{4} Is there a clean way to account for any/multiple emojis in a sentence so I can replace the surrogate pair with the function I have? Thanks!

问题 I read this blogentry regarding perl and how they handle unicode and normalization of unicode. Short version, as I understand it, is that there are several ways to write the identifier "é" in unicode. Either as one unicode character or as a combination of two character. And the perl program may not be able to distinguish between them causing strange errors. So that got me thinking, how does the Java editor in Eclipse handle unicode? Or java in general, since I guess thats the same question.
