trouble with UTF-8 input data with mssql_bind

Hi,


I'm using FreeTDS 0.82 to execute a stored procedure on a MS SQL Server 
2005. Unfortunately, I keep getting error messages while executing a 
stored procedure using mssql_bind.
Web server is Fedora 8, PHP 5.3.0, freetds 0.82, database server is 
called MSSQL.


While using the syntax:

EXECUTE  [procedure name] [parameter values with leading N when any 
varchar data]

Everything goes OK.
Client encoding is UTF-8, parameters are all nvarchars, it fails on a 
first nvarchar parameter (look at freetds.log).

freetds.log says:
"Error converting characters into server's character set. Some 
character(s) could not be converted"
"The incoming tabular data stream (TDS) remote procedure call (RPC) 
protocol stream is incorrect. Parameter 2 ("@user_agent"): Data type 
0xA7 has an invalid data length or metadata length."

I have searched through the internet, but I found no solution, how to 
get it working by using mssql_bind() function. If any of you could help, 
I'll be grateful. If you'd like to have more information, please ask, 
I'll try to post it.


With regards,
Tomasz Kurkiewicz
