Once again, because the problem still has not be solved, the urgent prayer to solve the "special character problem".
Any word, containing a special character (Ä, ö, ü, é, è, î....) copied from a MAC program (with the exception of Google Crome!) appears broken when pasted into a MC tag field.
In the example you can see in the appended pictures I wrote the tags in Metadatics and then imported them in MC. As you can see some of the tag fields show the name "Mäkelä" in the correct way, some not.
