This codec uses mappings to encode and decode characters.

Decoding mappings must map single string characters to single

Unicode characters, integers (which are then interpreted as Unicode

|
ordinals) or None (meaning "undefined mapping" and causing an

error).

|
|
string characters, integers (which are then interpreted as Latin-1
|
|
ordinals) or None (meaning "undefined mapping" and causing an
|
|
error).
|
|
|
|
If a character lookup fails with a LookupError, the character is
|
|
copied as-is meaning that its ordinal value will be interpreted as
|
|
Unicode or Latin-1 ordinal resp. Because of this mappings only need
|
|
to contain those mappings which map characters to different code
|
|
points.
