I'm sure there must be already an issue for this... the first problem is that
the apps seem to clip against
ascent+descent+some margin. This fails when the ink bounds of layouted glyphs
extend beyond these
typographic suggestions. Especially scripts with vertically stacked glyphs like
Thai, Hindi, etc. suffer
from this.
As you noted the second problem is that even if the requested font's
typographic line height would
perfectly accommodate any combination of its layouted glyphs then still all
bets would be off if glyph
fallback was involved.
So the root cause of these individual problems is that the clipping area is
calculated too simplistically.
I'm not even sure why individual lines get clipped? AFAIK an intermediate
VirtualDevice is involved to
prepare a line. Maybe painting directly would be beneficial.
Reassigning to the WriterEngine expert.

Just separate the people in the CC-line by a space (e.g. "victor21 zhf
fuxingwang")
