I'm using TeamViewer on Linux to control others machines with Linux and Windows and on both it is not working to send letters with accents (i.e. á é ã õ ...) or only accents ( ' ~ ` ).
Now I'm using:Linux Mint 19 TaraTV: 14.0.14470
But also happend with Linux Mint 18 and previous minor versions (14.X).
The clients is running different versions of TeamViewer, including 12.X, 13.X and 14.X
