deactivate any indexes used for the column. Find the rdb$fields record
that is the domain for the column (rdb$relation_fields -> rdb$field_source)
Change the type to 14 (better check that ... I think char is 14 and varchar
35, but my memory is fallible). Specify a length and a character length,
commit, then recreate the indexes.


We have answers.
