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.,
http://www.iana.org/domains/idn-tables/tables/sap_ca_1.0.txt). But I
guess Sarmad will know for certain.

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.
