Data.Text.CP437.Graphical

Simple conversion of Unicode Text to and from code page 437, with printable glyphs for the whole range. Our design choice is to print 0x00 as a space.

Unrepresentable unicode characters are converted to a null byte.

Text/ByteString

textToCp437 :: Text -> ByteString

Given a string of text, produce a bytestring containing valid CP-437 encoded data. If any UTF symbols are used that occur in CP437 they will be translated.

cp437ToText :: ByteString -> Text

Given a ByteString that is encoded with CP-437, will decode to a UTF Text, with all symbols converted.

Char/Word8

utfToByte :: Char -> Word8

Convert a single unicode character to a CP-437 byte.

byteToUtf :: Word8 -> Char

Convert a single byte into a unicode character.
