Is it?  I can't see that with ftview, neither at 72dpi nor 96dpi.

Anyway, I don't think that this is easy to handle.  Main reason is
that Vera has a lot of TrueType instructions which changes the shape
depending on the size.  For small sizes, it exaggerates the vertical
extent of the tilde so that the rasterizer actually displays a tilde.
The autohinter can't do that.
