Hi Michael, All,
I assume that we will need to define the context those combining marks are allowed. ... But I guess Sarmad will know for certain.
This discussion is published by IP in Section 4.5. Non-Spacing Combining Marks of the Overview and Rationale <https://www.icann.org/en/system/files/files/msr-2-overview-14apr15-en.pdf> document released as part of MSR-2 <https://www.icann.org/resources/pages/msr-2015-06-21-en> . I encourage you all to review it. It is noted in this section that: The actual set of combining marks allowable in the LGR will be smaller than the set included in the MSR, because it will be limited to those marks that are actually required for at least one combining sequence not expressible in NFC. In addition, where the number of such attested sequences is known and limited, GPs are encouraged to enumerate the sequences where feasible, rather than adding the "bare" combining mark to the repertoire. This would serve to prevent such marks from combining with every other allowed code point in the GP's repertoire. This suggests that where pre-composed form is not encoded directly, it is preferred to include the combining mark only with the desired code point(s) as a sequence <https://tools.ietf.org/html/rfc7940#section-5.1> to prevent over-generation.

MSR2 contains a number of combining diacritic marks, e.g. U+0323
COMBINING DOT BELOW. It might be that we find that some of the
languages that should be supported requires that code point in
combination with, say, "n", i.e. "U+006E U+0323". Let us assume that
there is no pre-composed equivalent code point.
We can then justify the inclusion of U+0323. Will then the Integration
Panel accept that code point in any context, or just in the specific
context?
I assume that we will need to define the context those combining marks are allowed. At least we did this for middle dot of the "ela geminada" in the Catalan language tables (see, e.g., <https://urldefense.proofpoint.com/v2/url?u=http-3A__www.iana.org_domains_id n-2Dtables_tables_sap-5Fca-5F1.0.txt&d=DwICAg&c=FmY1u3PJp6wrcrwll3mSVzgfkbPS S6sJms7xcl4I5cM&r=KTETvEaGPwPcawI-QmNa-kiv-ZBvdgyyLm-mxd028M4&m=dq_XzWWgeHkF r9WfH9IXK7WNh6-cBi-Ri4_TEqaDJkc&s=reu-ntqXFnNrZeDRDBLwSxLIFdJo9q4_2kUN7aPCiP 8&e> https://urldefense.proofpoint.com/v2/url?u=http-3A__www.iana.org_domains_idn -2Dtables_tables_sap-5Fca-5F1.0.txt&d=DwICAg&c=FmY1u3PJp6wrcrwll3mSVzgfkbPSS 6sJms7xcl4I5cM&r=KTETvEaGPwPcawI-QmNa-kiv-ZBvdgyyLm-mxd028M4&m=dq_XzWWgeHkFr 9WfH9IXK7WNh6-cBi-Ri4_TEqaDJkc&s=reu-ntqXFnNrZeDRDBLwSxLIFdJo9q4_2kUN7aPCiP8 &e= ). But I guess Sarmad will know for certain.
If the IP requires that we justify combining diacritic marks for every
context it will be allowed for, then we have to go language by
language to find all combinations to support.
If the IP accepts to include a combining diacritic mark for any
context as long as it is justified for one language, then we can go
code point by code point as long as we can find justification for all
Latin code points in MSR2 and we assume no more code points are needed.
If the purpose of our work is to create a Latin IDN table that
supports all listed languages (EGIDS value 4 or 5 as decided) then I
cannot see how we can achieve that without inspecting all those languages.
Going by language instead of going by character also has the advantage that we will be able to distribute the languages to members of the group. Then everybody can work with a certain sub-set of all languages. If we distributed the characters, everybody would have to get acquainted with every single language.
