[R] Problem with writing a CSV file in UTF-8 formate

[Matt Shotwell]

Duncan and I had nearly identical code examples in our replies. This is
becoming a theme. Great minds think alike??? :-)

UTF-8 is backward compatible with ASCII. Hence, if your "|" separated
table contains only ASCII, the UTF-8 encoded file may be
indistinguishable from an ASCII encoded file. Maybe notepad can't tell
it's unicode, and uses ANSI (codepage?) to represent its best guess.

Does your table contain non-ASCII characters?
