Weird interline spacing

Weird interline spacing

[Khaled Hosny]

[-- Attachment #1.1.1: Type: text/plain, Size: 432 bytes --]

In the attached file, loading the font with \setupbodyfont gives
narrower interline spacing than with font (you have to comment out the
\setupbodyfont line to see this), I'm not sure if this is normal, but
the first case gives different interline spaces from line to line. I
tested it with two different fonts.

\font does nothing with interlinespace at all

\setupbodyfont does set the interlinespace as defined by the bodyfont 
environment (2.8 ex by default with a 72:28 ht/dp ratio)

OK, however that was a side issue, my real problem is the variable
interline spacing, see the attached file; the first interline space is
considerably larger than the others, this seems to be due to the
diacritics on the second line. Shouldn't the interline space to be fixed
in all lines?

 Khaled

change the line distance, you could check it with \showgrid.

a distance of 4ex is enough, \setupinterlinespace[line=4ex]

Thanks for the tip, I just had the illusion that this is a new
behaviour.
