Character set AL32UTF8;

Question

Hello All,
I have oracle 10gr2 and i want to get support of Portuguese character set, for that , i suppose AL32UTF8 is recommended, but when i try to modify the character set i get this error.
SQL> select value from nls_database_parameters where parameter='NLS_CHARACTERSET';
VALUE
WE8ISO8859P1
SQL> alter database character set AL32UTF8;
alter database character set AL32UTF8
ERROR at line 1:
ORA-12712: new character set must be a superset of old character set
what should i do now? any idea?
thanks

here it is:
SQL> select news_detail from news_tbl;
NEWS_DETAIL

de Mo?ambique, Albertina Fruquia, esteve nesta quarta-feira, do dia 22 de Novemb
ro, na Secretaria de Log?stica e Tecnologia de Informa??o ( SLTI )para conhecer
o sistema de compras do Governo Federal Brasileiro e verificar a possibilidade d
e estabelecer acordos de coopera??o nessa ?rea.</p>

<p>Na opini?o da Directora Mo?ambicana, o Brasil tem uma experi?ncia importante
em compras p?blicas que pode colaborar com Mo?ambique nesta ?rea. Ela lembrou qu
e o pa?s Africano est? imlpementando um novo regulamento de compras que constitu
i o preg?o presencial, modalidade regulamentada no Brasil desde 2000.</p>

you can see that even in sqlplus the data is not shown the portugueses language chars, now what you think, that whether this data is stored wrong or either i can recover it by changing chars set or language?
