--- Comment #10 from Winfried Donkers <winfrieddonkers at libreoffice.org> ---
As already said in comment #4, LO uses 16bits for unicode characters, which is
not enough for the UniCode 5.2.0 (referenced to in ODFF1.2). Changing this
could have far-reaching effects in all sorts of places in the LO code. Anyway,
IMHO such a change would require an ESC decision.

As Excel 2016 has the same results as LO, interoperability would be affected
when LO is changed.

I suggest to set this bug report to RESOLVED-NOTABUG and create a new bug
report/enhancement request to change the UniCode typedef in the LO code.

Adding ERack to cc as he is the Calc expert.
