           Product: LibreOffice
           Version: 6.1.0.0.alpha0+ Master
          Hardware: All
                OS: All

Description:
Open the attached odt
Export To PDF(the result is attached)

the attached pdf is exported version of the attached odt but uncompressed by:
qpdf --stream-data=uncompress in.pdf out.pdf

all the characters in the odt is in 20pt

When you open that pdf in text editor(Of course you can open it in hex editor,
if you don't mind unreadability from not caring newlines),

you will see the following lines
BT
1 0 0 1 575.3 824.1 Tm /F1 20 Tf<01>Tj
1 0 0 1 575.3 804.1 Tm<02>Tj
1 0 0 1 575.3 784.1 Tm<03>Tj
1 0 0 1 575.3 764.1 Tm<04>Tj
1 0 0 1 575.3 744.1 Tm<05>Tj
1 0 0 1 575.3 724 Tm<06>Tj
1 0 0 1 575.3 704 Tm<07>Tj
1 0 0 1 575.3 684 Tm<08>Tj
1 0 0 1 575.3 663.9 Tm<09>Tj
ET

and

BT
1 0 0 1 550.3 819.1 Tm /F1 20 Tf<01>Tj
1 0 0 1 550.3 799.1 Tm<02>Tj
1 0 0 1 550.3 779.1 Tm<03>Tj
1 0 0 1 550.3 759.1 Tm<04>Tj
1 0 0 1 550.3 739 Tm<05>Tj
1 0 0 1 550.3 719 Tm<06>Tj
1 0 0 1 550.3 698.9 Tm<07>Tj
1 0 0 1 550.3 678.9 Tm<08>Tj
1 0 0 1 550.3 658.9 Tm<09>Tj
ET

so the differences in y-value of the matching positions in two lines are

824.1 - 819.1 = 5
804.1 - 799.1 = 5
784.1 - 779.1 = 5

all the same: 5 , *which should be 0 instead.*

emphasis mark is seemingly not exported to PDF

Differences between the adjacent characters in the same line, such as 824.1 -
804.1 were the same as the font size: 20

these relationship did not change when I set 12pt for the characters.

differences in matching positions was all 3, and the differences in the same
line were the font size:12

from I've seen, I guess this is coming from this thing-y.

Expected result should have emphasis mark on the right side of the characters
instead of top side. But possibly export to pdf does not consider this, and
emphasis marks to be shown were somehow clipped?

Steps to Reproduce:
Open the attached odt
Export To PDF
