// Package tcell provides a lower-level, portable API for building
// programs that interact with terminals or consoles.  It works with
// both common (and many uncommon!) terminals or terminal emulators,
// and Windows console implementations.
//
// It provides support for up to 256 colors, text attributes, and box drawing
// elements.  A database of terminals built from a real terminfo database
// is provided, along with code to generate new database entries.
//
// Tcell offers very rich support for mice, dependent upon the terminal
// of course.  (Windows, XTerm, and iTerm 2 are known to work very well.)
//
// If the environment is not Unicode by default, such as an ISO8859 based
// locale or GB18030, Tcell can convert input and output, so that your
// terminal can operate in whatever locale is most convenient, while the
// application program can just assume "everything is UTF-8".  Reasonable
// defaults are used for updating characters to something suitable for
// display.  Unicode box drawing characters will be converted to use the
// alternate character set of your terminal, if native conversions are
// not available.  If no ACS is available, then some ASCII fallbacks will
// be used.
//
// Note that support for non-UTF-8 locales (other than C)  must be enabled
// by the application using RegisterEncoding() -- we don't have them all
// enabled by default to avoid bloating the application unneccessarily.
// (These days UTF-8 is good enough for almost everyone, and nobody should
// be using legacy locales anymore.)  Also, actual glyphs for various code
// point will only be displayed if your terminal or emulator (or the font
// the emulator is using) supports them.
//
// A rich set of keycodes is supported, with support for up to 65 function
// keys, and various other special keys.
