New Comment:
cataphract, thanks for looking at this.
When I try your tests, neither line generates any output. I am using PHP
Version 5.3.5-1ubuntu7.2. Any ideas where I should look for a problem? Could
this be a server configuration issue? Thanks.

I can't reproduce that:
<?php
echo htmlentities("some\x80 text>", ENT_QUOTES | ENT_IGNORE, 'UTF-8',
false), "\n";
echo htmlentities("some\x80 text<", ENT_QUOTES | ENT_IGNORE, 'UTF-8');
gives the expected
some text>
some text&lt;

echo "test = " . htmlentities("some text", ENT_QUOTES | ENT_IGNORE, 'UTF-8',
false);
returns: test =
echo "test = " . htmlentities("some text", ENT_QUOTES | ENT_IGNORE, 'UTF-8');
returns: test = some text
The latter is the expected result, but why does adding the fourth parameter, to
prevent double-encoding, cause this function (and also htmlspecialchars) to
return the empty string? How can this be prevented?
I have a form that I want to redisplay to users until all their input has been
corrected, preserving their responses in the fields so they can start from what
worked. The users are international, with names containing lots of accent
marks and utf-8 characters, and some of the input is mathematical, with Greek
characters and such, so I want to assume the input is utf-8 to preserve all of
this, without messing it up on multiple passes. Thanks for your help.

Noted addition of ENT_IGNORE in the manual entries for htmlspecialchars and
htmlentities.
