I may have reported previously either in LibreOffice or OpenOffice
that for a character with "dot above", if exported to PDF, the dot
is too far away (hits the underang of letters on the line above it)
and a little bit to the left (looks a little misaligned),
but I could not find my own previous submission of the problem.

Now, actually, both for "dot above" and "dot below", the exported PDF
file has the dot a little too high and a little to the left of its
original position.  That is, those "dot above" is a little farther,
and those "dots below" are a little nearer, than their original positions.
If you set line spacing to 1.5 lines, then the export can be viewed without
much problem.

1. Type any letter or digit.

2. Select Format > Character > Effect > Highlight > Dot Above or Dot Below.

3. Export to PDF.

Thanks.
