Redmine

I would like to suggest adding a possibility of inserting "byte order mark" to the export CSV file. These bytes make life of windows users slightly easier, because the most of Windows* programs do not use UTF-8 as default charset for text files, so they cannot parse UTF-8 file correctly if use non english text. And users have to choose encoding manyally.

I would not like to suggest hard coding, because there are some limitations, several are described here: http://en.wikipedia.org/wiki/UTF-8#Byte_order_mark
I think, the right way is: to add an option which will control of inserting these bytes

following example of hard coding for my istallation
