otoh, if we never had a [] access anywhere, we could use utf-8 as a backend. The space saving (memory and therefor d-cache pressure) and the removal of the need to have 2 set of classes (one for SBCS and one for UCS-2) may actually be worth the exta cost in these cases (indexed access) Norbert _______________________________________________ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
