Yes, this issue is known, it only manifests when unicode.semantics=one
Here is an excerpt from the sources :
/* XXX: What about unicode type ??? Please test :) */
switch(Z_TYPE_PP(field)) {
case IS_STRING: {
It has been tested, as you also did, and it doesn't work. The code
should be ported to PHP6 Unicode but how to do it is out of my area of
expertise of working with Unicode+Zend :(

I did further testing, it seems the bugs shows up or not depending on
the blob field content itself :
- it works fine if the content is text (tried with both short strings
as well as 100 Kb+ ISO-8859-1 text files)
- it doesn't work with raw binary content (such as a JPEG file, however
short or long)
Also this is using MySQL 4.1 and InnoDB tables.

Works fine to me.
PHP 6.0.0-dev (cli) (built: Feb 12 2008 18:56:58)

Description:
------------
It seems using mysql_result to retrieve a blob doesn't work and returns
nothing (NULL). Using a different function like mysql_fetch_assoc
however does work properly, as does reverting to PHP 5 or retrieving a
non-blob column.
This is using Unicode semantics.
Reproduce code:
---------------
(...connect to DB)
$res=mysql_query('SELECT blob_column FROM table WHERE condition');
$var=mysql_result($res, 0);
print_r($var);
echo(gettype($var));
Expected result:
----------------
(random binary garbage) and a proper variable type (unicode or binary
?)
Actual result:
--------------
gettype returns NULL, and print_r echoes nothing.
