Remove dataset processing, allow only conversion

Fix support for both UTF8 and UTF16

Dont cast to char and append directly, but instead use `Encoding` class to convert the data in the buffer.
Also set Console output to UTF8 mode for cases where it outputs UTF8 but isnt set yet

Add support for '*' as a wildcard on first entry

Fix Display Error

Dont write Enumerable directly to console, use String.Join to convert it to string first
