encoding

问题 I am trying to redirect input in Powershell by Get-Content input.txt | my-program args The problem is the piped UTF-8 text is preceded with a BOM (0xefbbbf), and my program cannot handle that correctly. A minimal working example: // File: Hex.java import java.io.IOException; public class Hex { public static void main(String[] dummy) { int ch; try { while ((ch = System.in.read()) != -1) { System.out.print(String.format("%02X ", ch)); } } catch (IOException e) { } } } Then in powershell javac

问题 I have a scraper that is collecting some data from elsewhere that I have no control over. The source data does all sorts of interesting Unicode characters but it converts them to a pretty unhelpful format, so \u00e4 for a small 'a' with umlaut (sans the double quotes that I think are supposed to be there)*. of course this gets rendered in my HTML as plain text. Is there any realistic way to convert the unicode source into proper characters that doesn't involve me manually crunching out every

问题 I am trying to store the dictionary in my class Marker but it is throwing an error saying it is not encodable or decodable.

问题 I use TIdHttp to fetch web content. The response header indicates the content encoding to be utf8. I want to print content in console as CP936 (simplified chinese), but the actual content is not readable. Result := TEncoding.Utf8.GetString(ResponseBuffer); I do the same thing in python (using httplib2) without any problems. def python_try(): conn = httplib2.HttpConn() respose, content = conn.get(...) print content.decode('utf8') # readable in console UPDATE 1 I debugged the raw response and

问题 I have found the following encoding scheme in the POST requests at a login screen.
