A comment on wikimedia blog (https://blog.wikimedia.org/2017/09/20/bashkir-collation/#comment-244574 ) indicated that thai projects want better collation. A first glance indicates that uca-th is avalid collation, although i havent tested it.
- have native speaker verify that uca-th is correct (if you are native speaker please test the th collation at http://demo.icu-project.org/icu-bin/collation.html )
- get community concensuss on thai projects
- deploy uca-th to thai projects
