New description:
With a JSONField value with the following shape: {{{
my_object.my_json_field = {"en": "sôme téxt"} }}}
Doing the following queryset:
{{{MyModel.objects.filter(my_json_field__en__unaccent__icontains="text")}}}
does not match the above record, because Django interprets "unaccent"' as
a key to find in the JSON dict, whereas I meant the PostgreSQL
{{{unaccent}}} function.
By comparison, with a CharField,
{{{MyModel.objects.filter(my_char_field__unaccent__icontains="test")}}}
works as expected.
It seems that {{{ unaccent}}} is only supported on CharField and TextField
for now, but since what I am trying to do is possible in SQL, it might be
made possible as well using the ORM.

I am tagging QuerySet.extra because my workaround was to write the SQL
where clause I expected using {{{QuerySet.extra}}}.
