I don't know about you, but I kind of want to know exactly what's
getting written before I start.  In any case, neither of those choices
is UTF-8.

Try writing directly what's pointed by the pointer returned by -
UTF8String, or putting that into an NSData and using its
writeToFile:atomically: method.

1)  Do you start the file with a BOM?  (Check unicode.org to be sure,
but I think it's 0xEF 0xBB 0xBF.)

2)  Does your HTML have an encoding tag?  ("charset=utf-8" in a meta
tag)
