nvPY produces strange characters in produced text files

[magicnemo]

Same problem exists with ResophNotes also.

Solution is that UTF8 text files on Windows (at least my version of Win7) need BOM-character (some Markdown editors have that as an extra option like WriteMonkey). (http://en.wikipedia.org/wiki/Byte_order_mark)

Solution for nvPY when I tried is to alter notes_db.py:

Instead of the row: "with codecs.open(fn, mode='wb', encoding='utf-8') as f:" use this row "with codecs.open(fn, mode='wb', encoding='utf-8-sig') as f: "

i.e. add the extra "-sig" text. (Thanx to this page for the solution: http://stackoverflow.com/questions/934160/write-to-utf-8-file-in-python)

Thought you might wanna add this to main track...

A minor remark: I saw that there are a couple of other places in notes_db.py using the word 'utf-8', in those places they are used when reading/opening files. Don't know if it matters, but could be best to replace all text from 'utf-8' to 'utf-8-sig' in the file notes_db.py

Another remark, there is a discussion here whether BOM shall be added or not, http://stackoverflow.com/questions/2223882/whats-different-between-utf-8-and-utf-8-without-bom

Maybe make it user selectable so those whose Windows can not handle without BOM can select it in the user config file.
