You may be right, but there are some Windows-specific parameters,
as in the 'OS/2' table, and it might be possible to tweak the
settings for Windows without changing anything for non-Windows.
For example...

The ascender metric for Windows. [...]computed as the yMax for all
characters[...] used to compute the Windows font height and default line
spacing. For platform 3 encoding 0 fonts, it is the same as yMax. Windows will
clip the bitmap of any portion of a glyph that appears above this value.
[/QUOTE]
Hopefully, couldn't we just adjust this value or similar value somewhere, which
only Windows will use, to tell Windows that DejaVu's yMax is large, so it won't
clip things prematurely? Or is the problem much more complicated?

Thanks for replying. I'd appreciate it even if this can't be fixed;
but since other cross-platform fonts do not have the same problem,
there should be some easy way to solve this. I'll look into it myself too
if I have time.
