Blacken

Blacken is a Java library for Roguelike development.

It supports arbitrarily resizing the window.

It maintains a "preferred size", changing the font size as needed.

By default, all applications support Alt-Enter for fullscreen mode.

It strives to support Unicode well.

A cell contains a sequence of codepoints.

Codepoints may be outside the Basic Multilingual Plane or zero-width accents.

All key input consists of valid Unicode codepoints.

Special keys are handled by codepoints in "private use" planes.

Modifier keys are handled through a prefix character (like Unix systems handle Alt via the
Escape character).
