encoding

问题 I have to use an encryption algorithm using Base64 but when I researched online I find forums state it is an encoding algorithm. This has me confused. :( Is Base64 an encryption or encoding algorithm? How do we differentiate between the two except for the fact that one is publicly decipherable while the other needs a key for that? 回答1: It's an encoding algorithm (hence "Base64 encoding") to allow people to move data in an ASCII friendly environment (i.e. no control characters or anything non

问题 Im looking to convert special characters like smart quotes to HTML entities but without converting other HTML markup because I need HTML markup to work. For example, convert <div>NVH “noise”</div> to <div>NVH “noise” issues<div> Its strange that if I log this on my local environment I get “noise” with smartquotes but on server I got ?noise?. My local runs LAMP with php56. server ran 54 and 55. I upgraded to 56 still no luck. I think either something in php configuration or among other things.

问题 In my model I have a field defined like this: name = models.CharField(max_length=50) Then in admin panel if I try to insert a record with the name that contains characters like 'č', 'š', 'ž', I get the UnicodeEncodeError. 'ascii' codec can't encode character u'\u017e' in position 3: ordinal not in range(128) What is this? Why doesn't django use utf-8 for everything? 回答1: Django uses utf-8 for everything. I suppose that the error might be in the __unicode__() method of your model. You should

问题 I have a Celerra NS-20 that export a filesystem with cifs and nfs. The files are written by windows machines. When I mount the cifs in linux all filename special characters are ok, but when mount the nfs (same filesystem) the filenames special character are broken. Are there a way to mount the filesystem changing the encoding ? 回答1: We have the same issue with a new VNX 5300 and the resolution was to enable the NFSv4 protocol in the VNX, by default its only support v3. For that, edit: /nas

问题 Im trying to encode a simple string by the ENCODE()-function. Using a string it gives me text as output. But using a field it gives me BLOB. How can I get around BLOB and output text for encoded fields? Here's what happens: SELECT ENCODE('myText,'myPw') - Output : baddade4b04e // Goal = This + using fieldname SELECT ENCODE(Field,'myPw') FROM myTable - Output : [BLOB - 14B] What I've tried: SELECT CAST(ENCODE(Field,'myPw') AS CHAR(1000) CHARACTER SET utf8) FROM myTable - Output : Empty rows!

问题 I am new in thinking about binary numbers. I'm wondering if there is a way to encode 2 4-bit numbers (i.e. hex-encoded numbers) into 1 8-bit number. So if I had a and 5 as the hex numbers, that would be 10 and 5. Maybe there is a way to store that in 1 8 bit number, in such a way that you can get it out of the 8-bit number back into its component 4-bit parts. [10, 5]! = 15 15! = [10, 5] Wondering if there is such a way to encode the numbers to accomplish this. It seems like it is possible,

问题 I am trying to send the contents of an XML file from a handheld device (Compact Framework/Windows CE) to a Web API method in my server app like so (Client code): public static string SendXMLFile(string xmlFilepath, string uri, int timeout) { HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri); request.KeepAlive = false; request.ProtocolVersion = HttpVersion.Version10; request.Method = "POST"; StringBuilder sb = new StringBuilder(); using (StreamReader sr = new StreamReader

问题 I'm developing a Windows 8/8.1 JavaScript app. It basicallly is a port of our webapp. For deployment, I'm using grunt, grunt-contrib-uglify and grunt-contrib-cssmin (next to some more, but those are not connected to my problem. UglifyJS is used to package all my JS files and libs in a minified bundle for each. For the CSS it's the same using CSSmin. As the Windows app certification forces a UTF-8 encoding with signature (BOM), all my source files are encoded that way. I also did set the grunt
