iphone

I am using libxml2 in my iPhone app. I have an NSString that holds the pathname to an XML file. The pathname may include non-ASCII characters. I want to get a C string representation of the NSString for to pass to xmlReadFile(). It appears that cStringUsingEncoding gives me the representation I seek. I am not clear on which encoding to use.

I wonder if there is a "default" encoding in iPhone OS that I can use here and ensure that I can roundtrip non-ASCII pathnames.
