First, I’d like to thank Michael for his patience, at our meeting at ICANN82, as I tried to put my concern about the phrasing of our into words. Unsuccessfully. I hope I can do better here.

When the Latin Generation Panel was creating the RZ-LGR, with just a couple of exceptions we were looking at visual confusable similarity. That is, we compared a code point (ASCII letter or that letter plus one or more diacritics) to another. If, in a side by side comparison, we found it very difficult to distinguish between them, they were designated variants. If we could distinguish them, they were not variants. Note that, when one code point was just an ASCII letter, and the other was that letter plus a diacritic, there were no cases where they were variants. None. Zero.

So let's look at the type case which motivated our PDP: Quebec vs Québec. Clearly e and é are not visually confusable; the Latin GP already ruled on that. So what are we even looking at? Why are we here?

If a French-speaking resident of Québec is presented with Quebec (that is, without the diacritic), will it occur to him, even for an instant, that he is looking at a different word? Never. He will see it as an error, due to the lack of the diacritic – whether due to ignorance on the part of one of the English speakers that surround Québec in North America, or due to even a French speaker using a keyboard which doesn’t provide for diacritics. Wrong, but NOT different. They are not visually confusable, but rather functionally interchangeable/confusable.

The various other examples given in our direction from the GNSO Council all have the same characteristic. There’s no problem seeing the difference; no visual confusion. It’s just that the difference, in those cases, is not considered significant by the user.

Now there are doubtless some cases, in some languages, where the addition of a diacritic does result in a different word. But the question before us is, I think, do we try to go thru all the hundreds of languages which use the Latin script, trying to identify those cases? Or do we make a rule which can be applied across all cases involving a diacritic, whether they are real words or not? I submit that the latter is the only feasible course.

Hello all.

I would say “yes” to both your questions.

As I explained in previous mail exchanges, we should not base our decisions and distinctions in linguistic, semantic, morphological or otrhographic criteria. TLDs may be grammaticaly incorrect, or mean jut nothing in no language.

And indeed, what is a diacritic varies from context to context. In linguistic terms, it also varies historically: w was,and still is in some lalnguages, a variant, a diacritic version, of v. And u and v were just variants of the same character, as G amc C….

The point is not whehter they are considered proper charactars in a given alphabet or a modification/diacritic of another character. The point, for us, is that a set of the Latin charactr repoertoire iknon as ASCII does NOT require specicalencoding inthe DNS. While allthe rest does require althe IDN/punycode encoding. So when we say ASCII and diacrtitics we mean ASCII and non-ASCII (if they are similar enough to raise issues under the String Evaluation test which is a requirement for new gTLDs).

And indeed there may be more than one “similar” IDN/non-ASCII/string with diacritics which falls ntothe “too similar to be allowed” scenario, so the solution(s) we are toduscuss mayapply to more than 2 TLDs strings at once. Even if unlikely for practical (including financial) reasons.

Regards.
