Convert alternative Characterset from Oracle database

I have read the forum post and documentation about supported character sets of an external Oracle database.

However, I have a situation where I integrate with an Oracle database that has set its Characterset property to 'US7ASCII'. We see that special characters (for example é and à) are shown as question marks (even in View data).

Since the database is also used by other applications, it's probably not an option to change the characterset property.

Is there any way to correct the conversion?




you can use the oracle function convert

select ....., convert(column-name,'us7ascii','utf8') as ......,

from ....


you can read from the docs
