More modern and more Cocoa way? You mean something like this +
[NSString stringWithContentsOfFile:usedEncoding:error:] ;-)

This method attempts to determine the encoding of the file at path.»

If you're interested in determining the best encoding match for
text, look at the TextEncodingConverter.h header, which has
functions related to encoding sniffing. There may be more modern
techniques available, but I had used that almost a decade ago in a
formerly major web browser. It's not perfect, of course, but it
might be the best solution for your problem.

Actually, I don't recommend using CP1252 as the generic fallback
encoding like this.
The encoding does have gaps, and the handling of those invalid gaps
varies between conversion engines. CF/NSString treat the invalid
bytes strictly and return nil encountering those.
I wasn't aware it had gaps — I've never run into them. Where are
they?
<http://en.wikipedia.org/wiki/Windows-1252>
5 characters in the 0x80..0x9F range.
So, our recommendation now is to try UTF-8 first; then, try some
other encoding deduced from the context (user's localization,
intended source/destination of the data, etc). If all failed,
should try MacRoman as the ultimate fallback (the encoding has no
gap so never fails).
In the contexts I've been dealing with — data fetched over HTTP from
random websites — there hasn't been anything deducible from the
context (assuming the HTTP Content-Type already failed.) In that
situation MacRoman is not at all a good fallback as almost no Web
content uses it; CP-1252 or ISO-Latin-1 are the most likely
fallbacks after UTF-8.
I will agree with this if it's web content you're dealing with.
Although, just do a fallback to windows1252. Lots of site content
was
authored with that encoding and mistakenly marked as ISO_8859-1. But
that's a topic for another forum.
