Upgrading an existing GemStone database to use Unicode requires careful
planning and execution. There are significant differences from conventional
strings that affect how strings (Unicode or traditional) sort and compare.
[*Note that installing Seaside in an existing GemStone database will upgrade
it to Unicode*.]
The bug note for issue #46694
<https://gemtalksystems.com/data/bugnotes/46694.html> addresses some of
"When changing an existing application from the standard mode to Unicode
Comparison Mode, you must take steps to ensure any structures relying on
comparisons are rebuilt; indexes on strings must be rebuilt, sorted
collections on strings may need to be re-sorted, and dictionaries with
string keys may need to be rebuilt."
Chapters 5 and 7 of the 3.3 Programming Guide
discuss Unicode in the context of strings and of indexes.
