The following bug has been logged online:

Bug reference: 3030
Logged by: Dr. Axel Reimann

PostgreSQL version: 8.1.8
Operating system: Gentoo Linux, Kernel 2.6.19, glibc 2.5
Description: Unable to query SQL_WCHAR column via ODBC
Details:

I created a table via:

CREATE TABLE publisher
(
name character varying(80) NOT NULL,
address text,
CONSTRAINT publisher_pkey PRIMARY KEY (name)
)
WITHOUT OIDS;
ALTER TABLE publisher OWNER TO postgres;

whereas the database encoding is set to UTF8 and
inserted some data, lets say:
'New Publisher' 'new address'

If I query that table, e.g. via pgAdmin's query tool,
I can easily retrieve the entered information.
Running a corresponding query from an ODBC application,
I get the following 'unsupported type' error:

[ODBC][11736][SQLExecDirectW.c][138]
Entry:
Statement = 0x83f2820
SQL = [SELECT Name FROM Publisher][length = 26

The connection was made via ODBC's SQLConnectW function
and returned:
