win-1251 cyrillic support ?

hi,

I have setup postgres db with WIN ecnoding (i.e. win1251)...but when i enter
data the cyrillic is not preserverd and all that goes in/out the DB is garbage-characters ?
Why is this that way is there any solution ?

I'm entering data via web-perl app and via pgadmin3 ..

if any additional info is needed ?
