Reading or writing a line from or to a text file maybe a very common task in programming. The CTextFileIO class wants to simplify this task, whatever your text file encoding type be, and your program environment could be ANSI or Unicode. The class properly reads/writes a text file in ANSI, UTF-8, UTF-16 Little Endian, and UTF-16 Big Endian encoding. Its aim is to simplify read/write a line from/to a Unicode or ANSI encoded text file in a MBCS program or in a Unicode program. You don't have to bother about the file's encoding type or your program's environment, it does all this work for you. The class can read or write a text file created by Notepad or any Notepad compatible editor like UltraEdit or EditPlus in ANSI, UTF-8, Unicode, or Unicode Big endian encoding.
