Self Referrals problem with IDN-domain
we run an IDN-domain: xn--jobbrse-d1a.de = jobbörse.de
Some browsers interpreted our URL as jobbörse.de, some others as coded: xn--jobbrse-d1a.de
Universal Analytics is tracking all traffic comes from browsers which passes jobbörse.de as referral traffic and this increase our bouncerate extremly.
By using the old Analytics code there was necessary to add in the code the punycode URL (xn--jobbrse-d1a.de) for tracking all traffic from all browsers. In the Universal Analytics there is no possibility to add the IDN-domain.
Is there any solution to give information to Analytics that both domains, IDN coded and uncoded, are the same?
We have excluded referral traffic in SC but this was only hidden the referrals but doesn´t affedcted the bouncerate:
Can anybody help please?
