c# - Oracle ManagedDataAccess and special characters when logging in -

i've encountered issue oracle.manageddataaccess seems impossible use non-ascii connectionstring (non-ascii empirical guess).

this fine , dandy:

var cs = string.format("data source={2};password={1};user id={0}", "user", "pwd", "mydb"); var connection = new oracleconnection(cs); connection.open(); 

but not work (å, ä , ö swedish letters):

var cs = string.format("data source={2};password={1};user id={0}", "åäö", "lösenord", "mydb"); var connection = new oracleconnection(cs); connection.open(); 

and throws

oracle.manageddataaccess.client.oracleexception: ora-01017: invalid username/password; logon denied 

both users capable of logging on via sqldeveloper.

does know of way around this? or known limitation manageddataaccess (well, dataaccess) libraries oracle?

ninja stuff, ie using chr(int), hard when signing in..

edit:

also tested (ie adding quotes, oracleconnectionstringbuilder "="):

var cs = string.format("data source={2};password={1};user id={0}", "\"åäö\"", "\"lösenord\"", "mydb"); var connection = new oracleconnection(cs); connection.open(); 

i ran same problem , issue got fixed latest odp managed driver version september 16, 2016 (4.121.2.20150926).

be careful download 32bit section of oracle website (http://www.oracle.com/technetwork/database/windows/downloads/utilsoft-087491.html) oracle seems have missed add 64 bit section, latest version still october 2015. more information see question on oracle forums: https://community.oracle.com/message/14037653#14037653

makes kinda wonder though oracle to, since did not support language specific characters 3 years in managed driver...
