Edit: this issue was originally about the kerning between "tt" being too tight, but after testing I'm no longer sure and gave up because I'm not that knowledgeable about font design.

Describe the bug
Under v4, the word "written" looks wrong for some reason, initially I thought it's because the kerning between "tt" was too tight, but after testing words like "little" I realized increasing the kerning between "tt" might not be the answer.

To Reproduce
Steps to reproduce the behavior:

1. Display the word "written" with Inter v4
2. Kerning between "tt" feels way too tight, or is the kerning between "ri" too loose? I can't tell anymore.

Expected behavior
More natural looking kerning.
