// is available, and the rune cannot be displayed directly.

//
|

// New entries may be added to this map over time, as it becomes clear
|
|
// that such is desirable. Characters that represent either letters or
|
|
// numbers should not be added to this list unless it is certain that
|
|
// the meaning will still convey unambiguously.

// As an example, it would be appropriate to add an ASCII mapping for

// the full width form of the letter 'A', but it would not be appropriate

// to do so a glyph representing the country China.

// Programs that desire richer fallbacks may register additional ones,

|
// or change or even remove these mappings with Screen.RegisterRuneFallback
|

// Screen.UnregisterRuneFallback methods.

|
// Note that Unicode is presumed to be able to display all glyphs.

// This is a pretty poor assumption, but there is no easy way to
|
|
// figure out which glyphs are supported in a given font. Hence,
|
|
// some care in selecting the characters you support in your application
|
|
// is still appropriate.
