node.js - Text encoding problems in JSON.stringified() object -


I have index.html, which sends a text to a PHP code This is a node by PHP pdf (curl) JS redirects again to the server, which is inserted in JSON message (UTF 8-encoded) 

  // Node.js server file (APJS) - - Get JSN and it A & lt; Script & gt; To save it in the client JS render (index, {json: {string: "mystring"}} / Template to render (index.ejs) var data = & lt;% = JSON.stringify (json)% & Gt;;

so that I can pass those variables into data in JSON. JSON is a big way out of here, I only wrote a part that creates a bug: The string present here creates "Inwald character" JS bug. What should I do ? Which encoding / decoding / escaping should I use?

I have UTF-8 everywhere, because all my other strings work, even with German or Arabic characters. In this special case, it is "mystring" below which breaks the app:

If I remove characters in red circles then it works.

Here's the string I got in the JSON: 

  "Otto \ nTheater-, Konzert- und Gpb \ n \ u2028 \ u2028 Restore \ u00dfe 20 \ U2028 \ n51065 \ u00f6ln \ n \ nNote: 0000-000000-0 \ u2028 \ n Telefax: 0000-000000 \ n \ nEmail: address@mail.com \ u2028 "

Because this is the text entered by the user, I should handle it, like the characters I do not have access to the PHP part of the code, only for nodes and client js. How can I find and remove these characters in JS? 

  <% - JSON .stringify (data) .replace (/ [\ u0000 \ U00ad \ u0600- \ u0604 \ u070f \ u17b4 \ u17b5 \ u200c- \ u200f \ u2028- \ u202f \ u2060- \ u206f \ ufeff \ ufff0- \ uffff] / g, "\\ n")% & gt;

I have replaced invalid unicode characters (which are valid for JSON but not in JS code) with line breaks. This fixes the problem

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
