Problem with url links

android 7
latest joplin

Hello,
when I copy this link in opera I get
http://sypaade.gr/sypaade/2017/05/08/μηχανή-αναζήτησης-ελληνικής-νομοθεσ/

when I put the above link in a note and click on the link from within a note in opera, it takes me to

http://sypaade.gr/sypaade/2017/05/08/μηχανή-αναζήτησης-ελληνικής-νομοθεσ/

I dont if the problem is with opera, android or joplin.
