you should use:
1st. change your field type to NChar or NVarchar.
2nd.when insert to table,use 'N' + String like below:

SQLQuery = "Insert into INVHDR(COMP_CODE)  values(N'" & ExpRecSet!briefNameArabic & "')

EX:INSERT INTO UNicode_Table VALUES(1, N'Arabic_text');

hi mylim,

thanks for your reply.
but here situation is little different. I don't have the right to change the structure of oracle table. There the field type is 'varchar2'.

so any chances ??
Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

below is the PAQ Accept Answer:
char (size 1 to 8000) will take always the same space in database, ie a CHAR(50) field will always need 50 bytes even if you only store 'Hello' in it.
varchar (size 1 to 8000) will take exactly the space you store in the database, for the rest it is identical to char
nchar/nvarchar (size 1 to 4000). Basically the same as char/varchar, but you can store data in several character sets (chinese and greek can be stored in the same table.

binary/varbinary: same as char/varchar, but data is NOT interpreted using character sets, but as is.
text: size up to 2GB, handling is much different as from the above, except if you keep the data really short.
ntext: same as text, but again character set is taken into account.
image: same as text, but again with NO character set implications

Which is the best one:
char: typically for small and fixed-size values (SSN, ISBN etc)
varchar: typically for variable size data (names), but for relatively small data
nchar/nvarchar: same as above, but if you need different character sets
binary/varbinary:  if you store binary data (not text), ie encrypted data (like passwords)
text/ntext: store large texts (full html pages for example)
image: store files, images etc

My Opinion
If we have other way to store Unicode,then wat's the use of NChar,NvarChar ?
*maybe have other way,but already out of my knowledge,sorry.
