Build ID: 63150712c6d317d27ce2db16eb94c2f3d7b699f8
-- Need to transfer data from a Base table to a spreadsheet (Calc)
-- The data contain non Latin characters (in my case Greek)
-- If I follow the instructions in https://help.libreoffice.org/Common/Importing_and_Exporting_Data_in_Base
-- The greek characters are not tranferred properly

The attachment is a Base file with a single table exhibiting the issue

Below is a pasted text from the Calc file after attempting the export. (by the way, the copied table cannot be pasted as text, only as RTF and HTML)
