The libpcap format *is* binary. Believe me or see: 
http://wiki.ethereal.com/Development/LibpcapFileFormat

You may see packet *content* being text, e.g. if you capture an HTTP 
stream while getting some text/html files. The content inside the 
libpcap file is not being encrypted or compressed or something like 
that, so you may see plain text packet content as, well, plain text.
