[Latingp] Homoglyphs within Latin script

[Mats Dufberg]

In lower case, they are equal. My interpretation of "security" is that we must include some variant or contextual rules that prevent two TLDs only differing on those two code points.

I do not think we should try to interpret what IP thinks. We should propose a solution we think is correct.

Hi Michael,

They are not the same character. They look alike in lower case, but are different in upper case (i.e. disunification by case property). The IP briefly discussed this case of 01DD and 0259 in their feedback to our Principles document and suggested that these two should not be variants. Hence my question about more evidence.

    I'm not sure we need additional evidence, because in this case it's not
    mere "visual similarity" but those two are actually the same. And I
    don't think we have another choice in the case of homoglyphs, but to
    make them variants. On the contrary, I think we had to argue if we
    wanted to not make them variants.
