Aleksey Plekhanov commented on IGNITE-14545:
--------------------------------------------
{quote}it's not true. We need to override only those functions sensible to the
size of the character, like length, substring, strpos
{quote}
All mentioned above functions are sensitive to the size of the character.
Currently, with H2 (which uses {{v.getString().length()}}) we have the same
issue, so I think it's ok to have default Calcite implemented string function
and provide some new functions in the future to deal with 32-bit characters (by
separate low-priority ticket).
