I'm trying to read in a .zip file that holds a compressed .txt file. How can I check for the magic number 0x00BC? Thanks.
Edit: Sorry, should have specified that I'm trying to do this in java.

Is not the magic number CAFE BABE for class files? http://en.wikipedia.org/wiki/Java_class_file – Fedy2 Dec 03 '13 at 07:06

Magic number for zip is PK. http://en.wikipedia.org/wiki/Magic_number_(programming) – Fedy2 Dec 03 '13 at 07:07

@Fedy2 Whoops, disregard that. Sorry about that, dumb mistake. I guess that's just my immediate thought whenever I think of magic numbers. Question still applies though. Thanks for correcting that. – user2901181 Dec 03 '13 at 07:09

You want to read the first two bytes of the zip file or the first two of the contained file? – Fedy2 Dec 03 '13 at 07:12

Well the .txt was compressed into a .zip file. So the zip. – user2901181 Dec 03 '13 at 07:14

First two bytes from the ZIP file:
InputStream is = new FileInputStream(FILE NAME);
byte b1 = (byte)is.read();
byte b2 = (byte)is.read();
is.close();
First two bytes from the first compressed file:
InputStream is = new FileInputStream(FILE NAME);
ZipInputStream zis = new ZipInputStream(is);
zis.getNextEntry();
byte[] bytes = new byte[2];
zis.read(bytes, 0, 2);
zis.close();
