c++ - Renaming File With Unicode -

-

How do I insert Unicode characters in the filename? I have an ostringstream that I use to define the offline name through the file, but I can not use Unicode characters. What would be the easiest way to do this? Change it to Unicode format? And please tell me how I will do this. 

  / * This program tries to rename the file named  < / pre> 
 * CRT_RENAMER.OBJ to CRT_RENAMER.JBO. To be successful for this operation, a file named CRT_RENAMER. OBJes should be present and a file named CRT_RENAMER is present. JBO should not exist. * /    #include & lt; Stdio.h & gt; Int main (zero) {int result; Four old [] = "CRT_RENAMER.OBJ", new [] = "CRT_RENAMER.JBO"; / * Try renaming file: * / result = rename (old, newer); If (result! = 0) printf ("Could not rename '% s \ n", old); Else printf ("File '% s' has been replaced with '% s', \ n" old, new threads); }

Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
