General error;-8046 POS(76) Conversion from UNICODE impossible: A300 in recursive query

[Дмитрий Русанов]

I use MaxDB Version: 7.6.00.16 Build 016-123-109-428 for LINUX
Then I PACS.getInvestModel1 I have error

Auto Commit: On, SQL Mode: Internal, Isolation Level: Committed
General error;-8046 POS(76) Conversion from UNICODE impossible: A300
call PACS.getInvestModel1(1,'2Ж1',0)

if I not use function PACS.getRevision in recursive cursor  
PACS.getInvestModel1 call  is ok.
