The files were created in LjbreOffice Calc and export options are limited there. I've done this many times before but now it won't import when selecting utf8: UTF-8 Unicode:
/ Warning (3719): 'utf8' is currently an alias for the character set UTF8MB3, but will be an alias for UTF8MB4 in a future release. Please consider using UTF8MB4 in order to be unambiguous. /
A popup says that the file was imported but the data is not there so it clearly did not import it.
If I select utf8mb4: UTF-8 Unicode, it tells be that either the File is empty, Wrong file encoding was selected or detected or Field and/or line terminator do not file the file contents. The file is the same format as prior files so how I can I get it imported?
