How exactly do I get UTF-8 data into SQL Server on Windows via ODBC SQL Native Client 10.0?

[Richard Quadling <rquadling@xxxxxxxxxxxxxx>]

Hi.

I'm trying to get data into an MS SQL Server 2005 database. The data
is coming to me as UTF-8 encoded data. The data is primarily European
languages (so I've got a few accented characters), but I know I've got
Korean, Vietnamese and some Japanese coming later.

I'm using PHP 5.3.2-dev. The SQL Server is 2005 and the ODBC driver
I'm using is SQL Native Client 10.0

I've cut'n'pasted my table and SP below...

I'm calling the SP (all the phone numbers have been edited) ...

EXEC PhoneBilling.dbo.usp_HandleDirectory
	@s_PhoneNumber   = 'nnnnnnnnn',
	@s_Recipient     = N'Vergölst GmbH (Business)',
	@b_Rechargeable  = 1,
	@b_AllowOverride = 0


I've tried using ...

$s_Recipient = mb_convert_encoding($s_Recipient, 'UCS-2', 'UTF-8');

But this produces a string with nulls in which terminates the sql
string inappropriately.

I've also tried UTF-16

If I do nothing, the data in SQL is ...

45639	nnnnnnnnn	Vergölst GmbH (Business)	1	0	2009-10-07 08:29:42.137
45641	nnnnnnnnm	Vergölst GmbH (Mobile)	1	0	2009-10-07 08:29:42.150

If I execute the above EXEC call in MSSQL Server Management Studio, I
get valid results when I select the inserted rows.

48388	nnnnnnnno	Vergölst GmbH (Business)	1	0	2009-10-07 08:44:42.673
48389	nnnnnnnnp	Vergölst GmbH (Business)	1	0	2009-10-07 08:46:22.730

which is what I want.


I must be missing a trick as I'm sure it can't be that difficult.

I'm not in a position to try PHP6 yet.


Any suggestions would be gratefully received.


Regards,

Richard Quadling.
