Any ideas what is incorrect ?

create table jstone/fl2 (field1 char(20))
insert into fl2 (field1) values(Encrypt_RC2('TEST'))
select decrypt_char(field1) from fl2
Argument 01 of function DECRYPT_CHAR not valid.

what doesn't SQL like here??

The DECRYPT_CHAR argument-01 requires the CHAR to have been defined as FOR BIT DATA.

Try the following variation. An extra modification has the date\type attributes in a field, instead of as derived from a literal\constant as assigned by the SQL:

set encryption password 'AAABBB'
create table fl2
( field1 char(20)
, field2 char(40 /*20+16+4*/) FOR BIT DATA
insert into fl2 (field1) values('TEST')
update fl2 set field2=Encrypt_RC2(field1)
select field1, decrypt_char(field2) as field2 from fl2
