        Sure. On the other hand, we have:

git grep RTL_.*ASCII | wc -l
45122

        of this sort of thing that we know are ascii-only, and relatively fewer
utf-8 strings (none that I can think of off hand).

        I guess so. Of course, I like the idea of making UTF-8 a 1st class
citizen in rtl::OUString-land - it would be nice not to worry so much
about odd-ball character encodings, and assume that all char *'s are
UTF-8 in many ways.

        Of course, it would be even more wonderful, if, with some
template-magic, we could generate static rtl_uString structures that
would end up in the .rodata section, and got heap allocated only when
copied, with utf-8 -> UCS2 conversion on during a (reasonable time)
compile ;-) but that's a pipe-dream I suspect.

        Perhaps better to slowly move entirely to utf-8 strings anyway, which
brings us back to your proposal ;-) it is hard to see a benefit of UCS-2
really.

        ATB,

                Michael.
