Basically you have to look at two points:

  1. What is the encoding of your CSV file? For Cyrillic it could be typically ISO 8859-5, Codepage 1251, UTF-8 or even UTF-16 but I don't know.

  2. You need to tell the Oracle database the encoding. Typically this is done via the NLS_LANG environment variable.

I never used the Sql Developer Web interface, so I don't know where to set it. Perhaps you cannot change it and the tool forces your CSV file to be encoded as UTF-8. IN this case you have to convert your CSV file into UTF-8 before you upload it.
