I'm unsure as to where to post this and I apologise in advance if its in the wrong place.
I have a very old Acer Laptop which I have not used for a few years and my wife wanted to edit something our son had written.
I put the document from my computer onto a USB and placed it in the Acer and clicked onto it to open it and the following happened.

A square opened marked, “File conversion-Mikes doc.odt."
On that square another smaller square opened with a list running from top to bottom the top one showing as “Arabic (864)" at the top and the bottom showed "West European (Windows."
What ever I do the document showing gobbledygook.
