Dear colleagues,
I was trying to look for a specific reason why those code points representing click sounds have been excluded. Looking at the text of MSR-3, I was able to find only the following line of argumentation on page 23:
"In general, where code points are homoglyphs or near homoglyphs of code points that are not PVALID,
usually punctuation characters, the Integration Panel has not included such code points in the MSR.
In particular, the following code points are highly confusable with or outright homoglyphs of code
points, such as common punctuation characters like apostrophe or exclamation mark, that are not
PVALID in IDNA2008 or excluded for other reasons:"
I don't see however how the main argument that the code points we suggested are homogylphs or near homogylphs of such characters they consider punctuation characters. That argument may be valid in the case of U01C3 or U0242, but not the three code points we suggested. I think that this stance taken by IP is overly conservative and reinforces certain systemic biases in the DNS as part of the internet and that the entire point of our task is precisely to put and end to such biases and therefore I would like to raise this issue again.
I would suggest we submit a comment asking what their specific rationale for excluding these three code points is, and that clearly U01C2 for example is NOT a homogylph or near homoglyph of any punctuation character, just as U01C0 and U01C1. Otherwise, I would like to argue that following their approach 0069 (i.e. i) as well as any "near homoglyph" of it is a near homogylph of the exclamation mark and should be excluded equally.
Also, I have started working on the proposal, Bill, and I would like to add your text to it and I don't think it should be an appendix.
Best,
Meikal
