I got 4images UTF-8 problems

[timeriver]

OS:Winxp pro with sp2
apache version: 2.0.54
mySQL version: 4.1.12
php version: 5.0.4
mysql connection collation:utf8_general_ci
my 4images DB collation:utf8_general_ci

I had converted all 4images files into UTF-8 , but I found I can't "Add categories" in my control panel , how can I do ??
When I click the "Add categories" , the center frame appear nothing.
The IE charset encoding had set with Unicode(UTF-8).

But the "Setting" is working as I used before.

And I had tested for the default charset version of 4images , everything woks fine.

I found what the problem is.
When I click Add categories , I found a error msg on the error msg file.

[27-May-2005 23:17:24] PHP Parse error:  syntax error, unexpected T_STRING, expecting ')' in C:\Apache2\htdocs\cjh_4images_utf8\includes\search_utils.php on line 38

I had remove the content of convert_special function , and "Add categories" works.
But is it fine ?
Or what should I do ?
