(PHP 4, PHP 5)
utf8_encode — Encodes an ISO-8859-1 string to UTF-8
$data
   )
   This function encodes the string data to
   UTF-8, and returns the encoded version.
   UTF-8 is a standard mechanism used by
   Unicode for encoding wide
   character values into a byte stream.
   UTF-8 is transparent to plain ASCII
   characters, is self-synchronized (meaning it is possible for a program to
   figure out where in the bytestream characters start) and can be used with
   normal string comparison functions for sorting and such. PHP encodes
   UTF-8 characters in up to four bytes, like this:
   
| bytes | bits | representation | 
|---|---|---|
| 1 | 7 | 0bbbbbbb | 
| 2 | 11 | 110bbbbb 10bbbbbb | 
| 3 | 16 | 1110bbbb 10bbbbbb 10bbbbbb | 
| 4 | 21 | 11110bbb 10bbbbbb 10bbbbbb 10bbbbbb | 
dataAn ISO-8859-1 string.
   Returns the UTF-8 translation of data.
