Oracle SQL Developer environment encoding -

-

i have oracle sql developer (3.1.07) , i'm trying work database uses we8iso8859p1 encoding:

select * nls_database_parameters parameter = 'nls_characterset';

i have problems saving packages contains unicode symbols. when open saved package unicode symbols turned '¿'.

what settings have change make sql developer keep symbols? i've tried set environment encoding 'iso-8859-15' , other encodings, won't help.

if database encodes text non-unicode single-byte encoding (e.g. iso-8859), symbol not present on character table seen invalid , replaced placeholder. can't go that, information lost.

that can worked around when storing data, source code, cannot control how oracle encode strings.

if database configured use such encoding scheme you're not supposed write code violates rules.
