Not all applications need rendering

Well, several posts above, @vfbb (topic starter) mentioned TEdit as an exmple "to clarify the problem", which is obviously uses text rendering.

On Windows, you can use the UniScribe API to get the glyphs from UTF-16 sequences.
We did that for our https://github.com/synopse/mORMot/blob/master/SynPdf.pas library.

 

But it is not cross-platform at all!
ICU is huge, but the cross-platform way of using it. This is what we did in mORMot 2 - not for glyphs but for case folding, comparison and codepage conversions.

Check also https://github.com/BeRo1985/pucu/tree/master/src which is a pure-pascal Unicode library...
I recently found https://github.com/bellard/quickjs/blob/master/libunicode.h which is very well written, and eventually available in our mORMot2 QuickJS wrapper.

We finally have the solution to the problem. Feature added to Skia4Delphi library and works on all platforms. See the results:
