Question about Extended ASCII character set, and fstream

[Guest]

Hey all,

Quick question...been bugging me for some time, really. I have a console app, it does some things, and I want to save an array of text to a text file. The text consists of ASCII and extended ascii (codes 0 to 255). I am using ofstream to output, and this is the line doing the actual output:

outfile << screenbuffer.Char.AsciiChar;

Note that screenbuffer is an array of type 'CHAR_INFO', quick info of it here:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/base/char_info_str.asp

Anyhow, the output, when I open it up in Notepad, shows ASCII characters fine, but nothing from the extended set (the extened set characters are garbled... into other characters.) When I put some extended ASCII chars into notepad (by holding ALT and pressing some numbers), they appear ok. When I try to save the file, it tells me I need to save in Unicode format.

SOOOO, I cannot figure out how to output to a text file in Unicode format from my program. Any ideas?


Thanks in advance!
Andy

You have two choices:

1. Use wide char streams (std::wofstream)

or

2. Use unformatted output (basic_ostream<...>::write method)
