working on a new project between France and North-Africa, I'll need arabics collations on certain columns in many tables (the rest of database will be in french_ci_as, or french_ci_ai).

I know I can specifiy it in a post-deployement script, but this implies to create index likewise (alter column ... collate my_collation is forbidden if an index uses this column)

Is there another workaround ? (or a plan inside SF team dreams to add/modify column collation )

Thanks in advance
