Which Unicode fonts are available with grades/optical sizes comparable to Donald Knuth's awesome eight grades in Computer Modern Roman?

It would be great to get at least 3 options!

This question is a logical follow-up question to this popular question. Although this question is not targeting a specific problem, I think it will provide some really valuable answers for XeLaTeX and LuaLaTex users.

Finding out that Computer Modern Unicode does not have the optical sizes / grades of Computer Modern Roman was disappointing. As a linguist, using unicode characters makes things much easier.

My options are as follows:

  1. Use a unicode font that has many optical sizes / grades (like CM Roman)

  2. Use CM Roman and hope for the best

  3. Create a custom command for all instances of unicode input/output (e.g. phonetic transcripts)

Option 1 is the best option!

The Latin Modern font family, for one, would seem to meet all of your needs.
