Actually, I should have written "RISC OS DTP programs" rather than
word processors. The above is true for Impression and OvationPro, but
not for EasiWriter/TechWriter.

Yes, the line spacing rules are different in Impression. They are as I
outlined above: The resulting line spacing is independent of the font.
EasiWriter's default "Auto" linespacing follows a more sophisticated
rule based on the font's ascent and descent measurements, so the line
spacing depends on the measurements of the applied font. This is based
on the behaviour of MS Word. EasiWriter's line spacing mode labelled
"Exactly" is independent of the font.
I think I can see why the line spacing changes when going from Latin-1
to Latin-2. EasiWriter uses the Latin-1 E-circumflex glyph to measure
the font ascent, but in Latin-2 that codepoint happens to be
E-cedilla, which does not have an accent, so the measured ascent is
too small. There are much better methods to determine a font's metrics
nowadays. Unfortunately, that ancient approach cannot be changed
easily because it would change the layout of existing documents.
