Long descender issue for swashes


hello everybody,

i’ve just exported a font for testing and in the swash version I found a really deep descender (i’m testing on adobe apps).

I’m not sure but this may be caused by some letters like /p that have a long swash that go deep down below the descender line.
Which is the best practice in these situations? Do i have to force the vertical metrics (if yes, which is the way to do that)? Do i have to leave in this way?
Thank you in advance for any advice you can give to me.


Adobe apps determine the size of the selection rectangle as well as the bounding box by the font bounding box, i.e. the highest and lowest parts of any glyph in the whole font. The only way to have a shorter box in Adobe apps is to not have any glyph reach so low.
