More progress on &unimap - search by character name, and go-to-code-point (feature parity with windows' Character Map and BabelMap.)

I'm pleased with the speed at which it searches all 40,000+ char names. Was fully expecting to dive into SIMD intrinsics by now and implement a fast substring search algorithm like this one.

Next things I want to do are

• load fonts from the user's OS if possible (instead of embedding all of GNU Unifont into the binary lol)
• drag-and-drop characters onto other windows (Character Map/BabelMap feature parity)
• clean up/streamline the UI. (only really need 1 search bar that returns both characters and blocks in an intuitive fashion)

1 and 2 will require diving into Win32 finally
