$CharacterEncoding

specifies the default raw character encoding to use for input and output when no encoding is explicitly specified. Initially this is set to $SystemCharacterEncoding.

See the character encoding current is in effect and used in input and output functions functions like OpenRead[]:

• • $CharacterEncoding

By setting its value to one of the values in $CharacterEncodings, operators are formatted differently. For example,

• • $CharacterEncoding = "ASCII"; a -> b

• • $CharacterEncoding = "UTF-8"; a -> b

Setting its value to None restore the value to $SystemCharacterEncoding:

• • $CharacterEncoding = None;

• • $SystemCharacterEncoding == $CharacterEncoding
