If the input to HarfBuzz is identical, but the output isn't, it points to a HarfBuzz bug. > I don't think it is of any help but I attached two text files: bad-case > and good-case. bad-case has all the data for the clipped text, and > good-case for the non-clipped text (for the same font size, at least I > hope so...). It's hard to understand what you printed out, or where is the difference. It is best to print only the data for the characters for which you see display problems, because all the rest is just clutter. And in any case, please print the character with the data, otherwise it is impossible to know what to compare.
