UCA 16.0 delta 7

From Ken:

1. Todhri

Given all the complications of Kirat Rai to start off the day, I'm rewarding
myself before lunch by dealing with an easy case: Todhri. This is just a straight
unicameral alphabet, with no complications other than two letters that have
canonical equivalent sequences.

Move the relevant entries for Todhri (105C0..105F3), in code point order, into
unidata.txt, right after Vithkuqi. Apply the CONTRACTION pragma to the
two decomposed vowels, 105C9 and 105E4.

Generate allkeys.txt and verify that Todhri weights are as expected,
including the two contractions.

2. Sunuwar

This is another simple one, another simple unicameral alphabet with no marks,
and with the desired collation order the same as the code point order.

Move the relevant entries for Sunuwar (10BC0..11BE0), in code point order, into
unidata.txt, right after Tangsa (and ahead of the Kirat Rai I just added).
Leave the one punctuation sign to deal with later.

Generate allkeys.txt and verify that Sunuwar weights are as expected.

3. Gurung Khema

Gurung Khema is a bit more complicated. This one is an abugida, and it
has decomposition and contraction issues for the vowel signs.

First move all the relevant entries for Gurung Khema (16100..1612F),
in code point order, into unidata.txt, right after Sunuwar.

The 8 multi-part vowels with decompositions, 16121..16128, need to have
the CONTRACTION pragma, as the intent is for the vowels to all get
primary weights. 3 of the multi-part vowels, 16126..16128, have full
decompositions into sequences of three parts. Because of this, as for
Kirat Rai discussed above, those three need to have the full decompositions
added in their entries as secondary decompositions. The entries
affected are:

16126;GURUNG KHEMA VOWEL SIGN O;Mn;16121 1611F, 1611E 1611E 1611F;;;;;
16127;GURUNG KHEMA VOWEL SIGN OO;Mn;16122 1611F, 1611E 16129 1611F;;;;;
16128;GURUNG KHEMA VOWEL SIGN AU;Mn;16121 16120, 1611E 1611E 16120;;;;;

A replication note for when trying to build allkeys.txt with sifter in
the unicodetools: Before the sifter will work correctly for weighting of
abugidas, the Alphabetic property has to be updated for the repertoire in
question. In particular, all gc=Mn or gc=Mc vowel signs, consonant signs,
and length marks in abugidas need to be set explicitly to Other_Alphabetic
in PropList.txt first (and the relevant derivations be run based on that).
Otherwise, during the sift process, the sifter won't see these as
alphabetic and branch down the path for primary weights, but rather will
identify them as otherwise unaccounted for combining marks, and attempt
to give them secondary weights. Anusvaras and visargas also should be
set to Other_Alphabetic, but those are already bled off in unidata.txt by being
given explicit decompositions to generic marks.

Another piece of the puzzle is that nuktas and viramas (including killers)
should be given the Diacritic property in PropList.txt, but these are
more marginal for sifter behavior. Most nuktas are now bled off with
explicit decompositions, and the viramas are almost all picked up in
the sifter via their ccc=9 values. This could become a problem in the
future if SAH insists on ccc=0 for some newly encoded viramas, at which
point the sifter code may need an update to catch any combining
mark viramas (or conjoiners and killers) with ccc=0. The example we have for
16.0, in Kirat Rai, is not a problem, because that is gc=Lm, ccc=0,
so the sifter gets its Alphabetic status from gc=Lm and assigns it a
primary weight.

Generate allkeys.txt and verify that Gurung Khema weights are as expected,
with special attention to the vowel contractions.

4. Tulu-Tigalari

First move all the relevant entries for Tulu-Tigalari (11380..113D0),
in code point order, into unidata.txt, right after Grantha.

Put in the CONTRACTION pragma for the 3 two-part dependent vowel signs,
113C5, 113C7, 113C8. Do the same for each of the 4 two-part independent
vowel signs, 11383, 11385, 1138E, 11391.
Those aren't contiguous in code point order, so should use
multiple entries for the pragma, to make sure they don't pick up entries
that they shouldn't.

Now, checking against the detailed specification of the collation order
in the proposal (L2/22-031), invert the order of 113B3 LLA and 113B4 RRA,
so the collation order is RRA < LLA. That seems to be a deliberate choice
in the proposal.

Next move 113D1 TULU-TIGALARI REPHA into unidata.txt, immediately after
the RA (113AC). The repha is a separately encoded form of ra.

Note that for the Tulu-Tigalari vowels, there are deliberate encoding
gaps for short e and short o. Those might be added to the encoding later
on, in which case they would intercalate neatly in the gaps, and would
fit in the same places in the primary collation order. There is one
anomaly in the specification of collation in that it specifies the
primary order for vowel sign o, even though that is not encoded.
There is also a typo indicating: vowel sign vocalic ll << vowel sign ee.
That should be a primary distinction, like all the rest. Ignored.

The au length mark (113C8) only occurs as the second part of some
two-part vowels, and is basically would not be weighted alone
in most text, because it is basically bled by contractions that
form the weights for atomically encoded two-part vowels.
It makes more sense to give it a primary order
*after* the viramas, so I have reversed the position in unidata.txt,
as compared to the specification in the proposal. See the treatment
for Grantha, which has similar components.

The pluta (113D3) is not in L2/22-031. It was added later, based on
Srinidhi and Sridatta's L2/22-260.
L2/22-260 is silent about its ordering. It is a letter that serves
as a different kind of vowel lengthener. I'm giving it a primary order
after the au length mark. Again, see the comparable treatment of
the same component in Grantha.

The gemination mark (113D2) is also not in L2/22-031, but comes from
L2/22-260, which is silent about its ordering. However, the comparison
is made there to Gurmukhi addak (0A71), Khojki sign shadda (11237), and Soyombo
gemination mark (11A98). For DUCET, 0A71 is given a Gurmukhi-specific
secondary weight. The Khojki shadda is simply equated to the Arabic shadda.
The Soyombo gemination mark is given a Soyombo-specific secondary weight.
On balance, it seems best to just add a new secondary weight for the
Tulu-Tigalari gemination mark. I defer that to later, along with any
other new secondary weight additions required. Remember that Garay is
also introducing a gc=Mn gemination mark, so I have to figure out how to
deal with that one, too. So later.

Regenerate allkeys.txt, and verify that the Tulu-Tigalari weights
are as expected, with special attention to the various vowel contractions
and to the few other characters that receive primary weight not in
code point order, as noted above.

5. Ol Onal

Ol Onal is another easy one. It is a simple alphabet. The proposal (L2/22-151R)
specifies that the collation order is simply the same as the encoding order,
however, the discussion of the use of the two combining marks, MU (nasalization,
a dot above) and IKIR (lengthening, a dot below) suggests to me that it makes
more sense to give them secondary weights. That is, rather than what is
specified in the proposal:

A < A+MU < A+IKIR < A+IKIR+MU = A+MU+IKIR

what probably makes more sense for ordering is:

A << A+MU << A+IKIR << A+IKIR+MU = A+MU+IKIR

which would be accomplished better with secondary weights for MU and IKIR.

The proposal compares these two marks to the corresponding marks in Ol Chiki,
which are spacing and given gc=Lm, and the corresponding marks in Nag Mundari,
which are non-spacing diacritics. For best consistency, I think we should
follow the pattern of Nag Mundari, which gives the two non-spacing marks
secondary weights, rather than the Ol Chiki pattern, where the spacing
modifier letters get primary weights.

In any case, since the preferred solution involves assigning new secondary
weights, I defer the MU and IKIR to a later draft when I deal with those.

So for now, for the rest of the alphabet, I move all the letters (1E5D0..1E5ED)
and the HODDOND (1E5F0), in code point order, into unidata.txt right after Ol Chiki.

Regenerate allkeys.txt, and verify that the Ol Onal weights are
as expected.

I'll save Garay for the next delta.

233 more down, 771 to go.
