This is correct. I'm not a philologist, and I my main interest is
basically to assign correct character codes to two glyphs in a Greek
encoding which has been used for that purpose.

Well, I think that this nexus is based on existing documents, however,
I don't know them. My basic hope was that people on this list know
this emphasizing construction.

Yes, I'm searching grouping parentheses suitable for this.

I've mentioned in my mail that this is exactly what I want to use,
however, there isn't any sample usage given un UTR 25.

The mathematical brackets as mentioned in UTR 25 do group.

This is the idea, yes, to mark the start and end of the nexus (similar
to horizontal brackets or braces), and the text rendering engine does
the right formatting. Certainly, such a thing has already be encoded
in Unicode, I believe, at least for mathematical purposes.
