pt_pt keyboard with buildin accented letters (Çç,ã, etc.) they do not reflect in writer

Hello LO community
I am running OPENSUSE TUMBLEWEED, LO 5.3 factory.
In thunderbird, in this forum and other programs the letters from my keyboard display correctly, in libreoffice however they are replaced / substituted by:
ç = ç
Ç = Ç

This played up after a update on the tumbleweed around th 03/03/2017

Any idea?

For the record I am not looking to insert strange letter with a regular keyboard,
