I propose to include in the package a new feature WEB Unicode-Escape-Javascript -> Unicode.

For international characters in Javascript is used for special encoding non-Latin characters. Looks like: \ u0410 \ u0422 \ u0417 ....
For converting this encoding to Unicode, I needed a new function. I propose that its AEs in the package a new feature WEB Unicode-Escape-Javascript -> Unicode.

For converting this encoding to Unicode, I needed a new function. I have not found it, so I wrote in haste.

Maybe someone else will need.

I also want to note that some of the operations inside the function can be optimized. For example the plural multiplying by 16 can be replaced by bit shift.

String Javascript2Unicode(String s) {
	String res ;
	RegExp reg("\\\\u([0-9a-f]{4})",RegExp::MULTILINE);
	
	reg.Clear();
	
	int i_start,i_end,i_old=0;
	while (reg.GlobalMatch(s)) {
		reg.GetMatchPos(0,i_start,i_end);
		res << s.Mid(i_old,i_start-i_old-2);
		wchar wc[2] = {0,0};
		WString ws;
		String m = (String)reg[0];
		wc[0] = StrInt(m.Mid(0,1))*16*16*16
				+StrInt(m.Mid(1,1))*16*16
				+StrInt(m.Mid(2,1))*16
				+StrInt(m.Mid(3,1));
		
		ws = wc;
		String ss = ws.ToString();
		res << ss;
		i_old = i_end;
	}
	return res;
}

PS
Maybe there is already something like that? And I wasted 4 hours? Advise me if you know.
