Will the chairs ask the Integration Panel about that? Or do we as a GP need
to formulate that message?

Terms like "identical" are tricky. There is a character in the Armenian
script called "Armenian small letter oh" that looks like an italicized
"Latin small letter o", but according to Dalby's "Dictionary of Languages",
it is *not* the equivalent of the Latin small letter o"; instead, the
"Armenian small letter vo" (which looks like an italicized superscripted n)
is the equivalent of "Latin small letter o".

Please correct me if I'm wrong, but I thought this GP was for the use of
Latin at the root, and our decisions are supposed to be based on that. If
I'm right, then we can use the "single script" rule as a way of making our

Sure, that could be. However, given that instruction to "ignore cases where
the relation is based exclusively on aspects of visual similarity", that
doesn't seem relevant. Worse, there are numerous scripts that have
characters that will look like a vertical line ("Latin small letter l") or a
horizontal line ("hyphen minus" and "low line"). I would hope that each GP
with such a character is not expected to communicate with every other GP to
find if they have such characters.

> I think this is why we are being asked to comment.

Can we see the original request from the Armenian GP or from the Integration
Panel? It would help us decide how best to respond.
