If we do not want to use Uniscribe, just good old GDI,

Why not? Does U++ also takes care of devices that rely exclusively on GDI?

I guess it is about a) minimising changes in the code b) implementing in other platforms.

I believe we should do this in several phases:

Phase 1: Moving to code to utf8 (that is String instead of WString) and 32-bit codepoints support.
Phase 2: Basic combining characters support
Phase 3: Advanced text layout

for phase 3, we can either decide to use platform specific library (Uniscribe/pango), which would mean encapsulating it to something platform independent, or just use Harfbuzz on all platforms, which I guess will require dealing with glyph metrics and presence.
