StreamWriter erroneous characters

Question

Having an problem where streamwriter is producing erroneous characters in a csv that I\'m producing. The characters,  , only appear at the start of the file:

Answer 1

Those are probably characters designating that the file is unicode, and not ansi.

Are you opening the file as an ANSI file, in a text editor? If so, that's why you're seeing the characters. Either try opening it as unicode, or set your encoding to not be unicode.
