I am converting UTF8 string "Rø" to NSString using

get nil as a return value:
(gdb) p utf8_str

That is not a valid UTF-8 string. The UTF-8 encoding of "Rø" would be
"R\303\270" (that is, you're missing a byte).
(gdb) po theString
Cannot access memory at address 0x0
Is there a canonical way to convert wchat_t to NSString?
And furthermore, you shouldn't be using wchar_t to store UTF-8.
UTF-8 doesn't use wide characters. The utf8_str that you printed
above may have the bytes in the proper order or it may not depending
on endianness.
