TeraByte Unlimited work: ASCII to ANSI Converter

A recent order given by TeraByte Unlimited was to develop an ASCII to ANSI (and reverse) Converter.
The converter should be a Windows program converting text files between the ASCII and the ANSI character set.

The background to the program is that Windows and DOS have different character sets, so extended characters (all over 128) are displayed differend under Windows and DOS.
You sometimes see that when you're playing old DOS games and opening the readme.txt, license.txt or other documentation written under DOS. To display them correctly, they have to be converted, and this is the job the program does.

TeraByte Unlimited is a software company specified in Operating System Products.
Their main product is BootIt NG, which is a very good tool for IT System Professionals (for different solutions like backup, restore, partitioning, etc.).
For more information about TeraByte Unlimited, visit their website at http://www.terabyteunlimited.com/.

The Converter can convert between following character sets:

• ASCII Codepage 437
• ASCII Codepage 850
• ANSI Codepage 1252

ASCII Codepage 437 is the american DOS character set, ASCII Codepage 850 the european.
ANSI Codepage 1252 is the default codepage if not used UTF.

Note the program (Source Code and binary executable) is owned by TeraByte Inc., so there is no download available by Vienna Computer Products.
You can contact support of TeraByte Unlimited if you have interests in it.

The program was developed in Visual Studio 2005 Professional Edition, in C++ (bare Win32 application without use of frameworks).
A nice feature the program is a command line mode, for automatic scripting.

Here are some Screenshots about the work:
