help with Oracle ISO-8859-1 to Yii with UTF-8


I try to read correctly the database Oracle with the charset ISO-8859-1, but the result of query data prints the chars �.

The production charset database Oracle can’t been changed, is requeriment ISO-8859-1.

All application yii runs correctly, but the special chars shows badly.

Please, I need suggestions.



I can find the method to connect to ORACLE with ISO-8859-1 with Oracle Instant Client and the OciPDO.








Oracle, internally converts ISO-8859-1 to UTF-8.
