I need to import in database paas

we have latin american spanish database character:

select value from v$system_parameter where name = 'nls_language';

LATIN AMERICAN SPANISH

But we don't have the option to change territory or languange during paas database creation in OCI.

I have lost of data like accents and special characters á é í, ñ etc

We like to import with latin american and use the same interface without changes

Thanks sirsand madames
