Description

Method CmpSeabaseDDL::updateTextTable() takes a string, splits it into chunks of a maximum size and inserts them into the TEXT table. I have not yet verified that this problem actually can occur, but I think there is a possibility that the method will split a multi-byte UTF-8 character in the middle and will get an error. To fix this, we should use method findStartOfChar() in file sql/common/csconvert.h to find a good point to split the text.
