问题 So I'm trying to download a pdf file from a website with my script but the problem is that the file gets broken in the process and I'm pretty sure it's because of wrong encoding being used. I'm using request lib for downloading the file and I've set the Content-type to application-pdf My code is pretty simple:4 var fs = require('fs'); var request = require("request"); request({uri: 'xxxxxxxxxxxxxx.pdf', headers: { 'Content-type' : 'applcation/pdf' }} , function (error, response, body) { if (

Removing control characters from a UTF-8 string

由 我的未来我决定 提交于 2020-01-11 04:30:48
问题 I found this question but it removes all valid utf-8 characters also (returns me a blank string, while there are valid utf-8 characters plus control characters). As I read about utf-8 , there's not a specific range for control characters and each character set has its own control characters . How can I modify above solution to only remove control characters ? 回答1: I think the following code will work for you: public static string RemoveControlCharacters(string inString) { if (inString == null

Conversion in .net: Native Utf-8 <-> Managed String

由 半城伤御伤魂 提交于 2020-01-10 10:17:49
问题 I created those two methods to convert Native utf-8 strings (char*) into managed string and vice versa. The following code does the job: public IntPtr NativeUtf8FromString(string managedString) { byte[] buffer = Encoding.UTF8.GetBytes(managedString); // not null terminated Array.Resize(ref buffer, buffer.Length + 1); buffer[buffer.Length - 1] = 0; // terminating 0 IntPtr nativeUtf8 = Marshal.AllocHGlobal(buffer.Length); Marshal.Copy(buffer, 0, nativeUtf8, buffer.Length); return nativeUtf8; }

Swift 3 method to create utf8 encoded Data from String

由 随声附和 提交于 2020-01-10 08:41:04
问题 I know there's a bunch of pre Swift3 questions regarding NSData stuff. I'm curious how to go between a Swift3 String to a utf8 encoded (with or without null termination) to Swift3 Data object. The best I've come up with so far is: let input = "Hello World" let terminatedData = Data(bytes: Array(input.nulTerminatedUTF8)) let unterminatedData = Data(bytes: Array(input.utf8)) Having to do the intermediate Array() construction seems wrong. 回答1: It's simple: let input = "Hello World" let data =

C++ iterate or split UTF-8 string into array of symbols?

问题 Searching for a platform- and 3rd-party-library- independent way of iterating UTF-8 string or splitting it into array of UTF-8 symbols. Please post a code snippet. Solved: C++ iterate or split UTF-8 string into array of symbols? 回答1: If I understand correctly, it sounds like you want to find the start of each UTF-8 character. If so, then it would be fairly straightforward to parse them (interpreting them is a different matter). But the definition of how many octets are involved is well
