Fixed in revision #14641.

Unpacking fonts into .TeXmacs/fonts/unpacked/ leads to occasional inconsistencies in the font characteristics, which are then reported in the 'Flags' field of the PDF 'FontDescriptor' objects.

First, I've modified FontDescriptorWriter::CalculateFlags so that it returns 4 for this font: the PDF is displayed correctly by AcrobatReader, Ghostscript (with warnings), but not by macOS Preview.

Therefore, I've added the font into TeXmacs/fonts/pdf-font-issues.scm: it is now converted to bitmap T3 fonts.

On macOS, text set in the Helvetica Neue font does not display correctly when exported to PDF. Please see the attached files for comparison.
