Read the file in binary mode into a buffer. Then use ::MultiCharToWideChar to convert the text into the desired format (use ::WideCharToMultiChar to convert UTF-16 to ANSI).

If the encoding of the file is unknown, it can be detected by checking for BOM (Byte Order Mark, present with UCS-2 / UTF-16 and UCS-4 / UTF-32 files, optional with UTF-8 files), and UTF-8 validity checks. If no check matches, it is usually an ANSI encoded file. There are some libraries for codepage detection of ANSI files. However, these detections are guessers that usually return multiple possible codepages.
