DTS (international Question)

Quick background....
I have a file that is currently in Bulgarian (not unicode) that we want to import into a development environment for testing. However, the only way I can view the file as "non-gibberish" is for me to switch my local settings (on the OS) to Bulgarian. Then of course the file is readable in Bulgarian.

Now they have sent the following snipet of code asking if I can somehow add this to the DTS package? The purpose of this code is to...

They're sending me a C# routine to transpose the 10 or so Bulgarian-specific characters in the text fields.

They hope we can include this routine in the DTS package.

Here is the code....

private string StrFix( string InStr )
{
string Result = InStr;
Result = Result.Replace( 'x2591', 'ð' );
Result = Result.Replace( 'x2592', 'ñ' );
Result = Result.Replace( 'x2593', 'ò' );
Result = Result.Replace( 'x2502', 'ó' );
Result = Result.Replace( 'x2524', 'ô' );
Result = Result.Replace( 'x2561', 'õ' );
Result = Result.Replace( 'x2562', 'ö' );
Result = Result.Replace( 'x2556', '÷' );
Result = Result.Replace( 'x2555', 'ø' );
Result = Result.Replace( 'x2563', 'ù' );
Result = Result.Replace( 'x2551', 'ú' );
Result = Result.Replace( 'x255d', 'ü' );
Result = Result.Replace( 'x255b', 'þ' );
Result = Result.Replace( 'x2510', 'ÿ' );
Result = Result.Replace( 'x2552', '¹' );
return Result;
}


My questions... (as I'm not familiar with C#)

1. Do you guys see anything I'm not?
2. Is it possible to add this code to DTS package and have it change the 10 characters?
3. Wouldn't this be easier if their sample was in unicode?

Thanks in advance
