I understand what you mean and I tried it, but it doesn't work! On the countrary if I leave my script untouched it properly works: html page source (as it is shown by firefox 2) shows multibyte characters as they are, that is it doesn't make use of the corresponding html entities. Sorry I don't understand why I should encode data again. Probably you mean that I should process data into binary if I send them back to the database.
That is the un-encoded and encoded output: 
  <!DOCTYPE html
	PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
	 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en-US" xml:lang="en-US">
<head>
<title>xxx</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>

r.1,1	1 ʾà-da-umtúg-Ⅱ 1 aktumtúg 1 íb-ivtúg sa₆ dar

r.1,2	NI-ra-arki

r.1,3	2 ʾà-da-umtúg-ii 1 ʾà-da-umtúg-i
and this if the encoded output: 
<!DOCTYPE html
	PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
	 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en-US" xml:lang="en-US">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>

r.1,1	1 ʾà -da-umtúg-Ⅱ 1 aktumtúg 1 íb-ivtúg sa₆ dar

r.1,2	NI-ra-arki

r.1,3	2 ʾà -da-umtúg-ii 1 ʾà -da-umtúg-i
Even if these lines are not intellegible (it is a III millennium b.C. lenguage) only the first example is correct.
