Illegal characters in field name crashes database
-------------------------------------------------

                 Key: CORE-1251
                 URL: http://tracker.firebirdsql.org/browse/CORE-1251
             Project: Firebird Core
          Issue Type: Bug
          Components: Charsets/Collation
    Affects Versions: 2.0.1
         Environment: Embedded server (probably others too)
            Reporter: Poul Dige
            Priority: Minor


Trying to input an illegal character (e.g. danish letters =C3=A6,=C3=B8,=C3=
=A5) in a field name crashes the program with

Arithmetic overflow or division by zero has occurred.
arithmetic exception, numeric overflow, or string truncation.
Cannot transliterate character between character sets.

Afterwards the rdb$relation_fields.rdb$field_name is impossible to address =
for the table.

Running the following SQL will fix the problem:

update rdb$relation_fields
set rdb$field_name =3D 'NewFieldName'
where rdb$relation_name =3D 'NEW_TABLE'

However, I guess illegal characters should be caught by the engine before g=
oing into the rdb$relation_fields.rdb$field_name :)
