Question

How to convert ANSI to UTF-16 LE ( little_endian) ?
We need a way to translate into any of these languages.

Answer 1

little endian - after each ASCII character, insert a character with code 0. big endian - before each ASCII character, insert a character with code 0.

Answer 2

var buffer = Encoding.Unicode.GetBytes("Привет");

Answer 3

In WinAPI , MultiByteToWideChar is available for all languages.

Answer 4

var asciiBytes = File.ReadAllBytes(fileName); // допустим, что мы читаем текст из файла.

var text = Encoding.ASCII.GetString(asciiText); // Переводим байты ASCII в текст
var utf16leBytes = Encoding.Unicode.GetBytes(text); // Переводим текст в байты UTF-16LE

You may not need Encoding.ASCII, but Encoding.GetEncoding(1251), for example, if you really need win-1251.
