utf-8

问题 I'm receiving data as utf8 from a source and this data was originally in binary form (it was a Buffer ). I have to convert back this data to a Buffer . I'm having a hard time figuring how to do this. Here's a small sample that shows my problem: var hexString = 'e61b08020304e61c09020304e61d0a020304e61e65'; var buffer1 = new Buffer(hexString, 'hex'); var str = buffer1.toString('utf8'); var buffer2 = new Buffer(str, 'utf8'); console.log('original content:', hexString); console.log('buffer1

问题 As the next step for my happily solved problem (Not understanding why WinHTTP does NOT authenticate certain HTTPS resource) I need to prettily parse obtained CSV. At the moment I use the following solution: If HTTPReq.Status = 200 Then If FSO.FileExists(CSV_Path) = True Then FSO.DeleteFile (CSV_Path) Set FileStream = CreateObject("ADODB.Stream") FileStream.Open FileStream.Type = 1 FileStream.Write HTTPReq.responseBody FileStream.SaveToFile (CSV_Path) FileStream.Close ActiveWorkbook

问题 I have a fixture (json) which loads in development environment but fails to do so in server environment. The error says: " DatabaseError: value too long for type character varying(50) " My development environment is Windows & Postgres 8.4. The server runs Debian and Postgres 8.3. Database encoding is UTF8 in both systems. It is as if unicode markers in the fixture count as chars on the server and they cause some strings to exceed their field's max length. However that does not happen in the

问题 I used to have this as one of the options (4th param) passed to PDO constructor: $aOptions[PDO::MYSQL_ATTR_INIT_COMMAND] = "SET NAMES utf8"; But just found that it does not work on certain php versions on Windows (does not work in 5.3) due to some bug. Now I need to run SET NAMES utf8 using either $pdo->exec("SET NAMES utf8"); or $pdo->query("SET NAMES utf8"); right after the instantiating the pdo object. So, which one should I use - exec() or query()? 回答1: When using PDO::EXEC the result

问题 I have a JSP page whose page encoding is ISO-8859-1 . This JSP page there is in a question answer blog. I want to include special characters during Q/A posting.

问题 I am trying to get a java.net.URI object from a String . The string has some characters which will need to be replaced by their percentage escape sequences. But when I use URLEncoder to encode the String with UTF-8 encoding, even the / are replaced with their escape sequences. How can I get a valid encoded URL from a String object? http://www.google.com?q=a b gives http%3A%2F%2www.google.com... whereas I want the output to be http://www.google.com?q=a%20b Can someone please tell me how to

问题 Closed . This question needs details or clarity. It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post. Closed 4 years ago . Can this be done using a method similar to this one: As long as the current element of the string the user input via scanf is not \0, add one to the "length" int and then print out the length. I would be very grateful if anybody could guide me through the least complex way possible as I am a

问题 Apparently SSIDs can contain UTF-8 chars and also control characters etc. IIUC to contain UTF-8 chars they must specify the SSIDEncoding field. I was under the impression that I can only get ASCII bytes till now. How should I handle the situation in Android ? Namely, how can I check the SSIDEncoding field from the ScanResult ? Do I need to ? Also what does ScanResult.SSID contain in these cases ( including the case an SSID includes non printable characters ) ? Related Why can't I detect a

问题 I am retriving data from oracle11g and displaying the data on IE8 and IE9 browser, but the couldn't display some special characters (eg. é) In my webpage, I have explicitly declare 'UTF-8' encoding. For my tomcat webserver, the server.xml <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8" useBodyEncodingForURI="true"/> I read some other questions in stackflow, they mentioned to also ensure the database connection is using 'UTF-8' too.
