Letter J starts too far to the left, causes alignment and clipping problems

The letter "J" in Open Sans extends past the left edge of where it should. This causes several problems:

- In HTML, it will be clipped in containers with `overflow: hidden`. Example: (copied from https://github.com/google/fonts/issues/4266)

- It will look out of alignment with other fonts. Example: the top line is Open Sans, the line below is another Google font, [Inter](https://fonts.google.com/specimen/Inter)


This doesn't seem be to specific to web clients, because here's the same issue showing up in Microsoft Word (on MacOS). Note the J extends past the left edge of the caret.

This issue is a dupe of https://github.com/google/fonts/issues/4266 but this problem seems to be font-specific so I guessed that its natural home would be here instead of in the general Google Fonts repo. Feel free to close whichever one of these issues is in the wrong home.

If a fix is straightforward, I'd be happy to submit a PR but would need some direction as I know zero about building fonts!
