1363ac4a24 demo: in font book, ask font what characters are supported 
This replaces manual lists with a call to ab_glypgh::Font::codepoint_ids
plus names from the unicode_names2 crate.

Use old 1.51 toolchain instead of bleeding edge (#505) 
* Use old 1.51 toolchain instead of bleeding edge

1.52 and 1.53 has problems with incremental compilation,
so some people chose to stay on 1.51 for now.

So let's make sure egui supports 1.51 for a while!

* Update to cint 0.2.2 to get rust 1.51.0 compatability
