Is there a way to format the text in the following link that appeared in
today's digest? The code toward the bottom is all run together. I would
edit to correct it if that were possible.
Thanks!

The trick here is to replace the above line with:
print(String(validatingUTF8: buf))
`fgets` sets up `buf` to hold a C string, so you have to convert it to a
Swift string. How do you do this depends on the encoding of the bytes. If
you expect the C string to be UTF-8, then `String(validatingUTF8:)` is the
way to go.IMPORTANT: This conversion can fail, which is why the above will print a
bunch of optional strings, and you will have to decide what to your program
should do when it does.* * *
btw This question came up recently. See the thread for other suggestions
about how to handle it.<http://article.gmane.org/gmane.comp.lang.swift.user/1943>
