tcpdump -A -s 0 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)'
2. To monitor HTTP traffic including request and response headers and message body from a particular source:
tcpdump -A -s 0 'src example.com and tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)'

Utf8 string encode/decode using regular expressions
/**
* Encodes multi-byte Unicode string into utf-8 multiple single-byte characters
* (BMP / basic multilingual plane only).
*
* Chars in range U+0080 - U+07FF are encoded in 2 chars, U+0800 - U+FFFF in 3 chars.
*
* Can be achieved in JavaScript by unescape(encodeURIComponent(str)),
* but this approach may be useful in other languages.
*
* @param {string} unicodeString - Unicode string to be encoded as UTF-8.
