Teradata BTEQ logon with Latin Character SET

Hi All,
 
I am unable to set the Session to Latin.
I am using TD 14 & trying to logon from Unix terminal using below command:
bteq -c Latin1 .logon server/user,pwd
(Note: i am able to set the same for Acii which is default or utf8 using "bteq -c Ascii" or "bteq -c utf8)
 
I referred below links

Tried using
LATIN1_0A/ LATIN1252_0A/ ASCII-LATIN/ iso8859-1 / L1 with "bteq -c "& none worked.
Also tried logging in using ASCII and then use
.SET SESSION CHARSET 'name'
In both the case, I am facing below error.
 *** CLI error: MTDP: EM_CHARNAME(227): invalid character set name specified.
 *** Return code from CLI is: 227
 *** CLI error: MTDP: EM_CHARNAME(227): invalid character set name specified.
 *** Return code from CLI is: 311
 
Can anyone tell me how to set my TD session to MS Latin1?
 
Thanks
