Accented letters on V1R3 for Linux

I've been using Draftsight for Ubuntu every day for the last two years. That means I'm not a freshman on the topic.

For some reason with the new text editor on V1R3 I'm not able to write accented letters like ã or á anymore. It comes out as ~a and 'a.

On Facebook someone said he cannot write polish letters as well.

I've just installed Ares CAD for Linux (wich is Draftsight compilation 2.198) and the accented letters are ok.

Is there a reason for this? How can I solve the problem?

Thank you for your time
