System.UTF8IO defines the same entities as System.IO but with UTF8 text I/O operations.

System.UTF8IO re-exports System.IO.UTF8 and System.IO but hides the duplicate definitions (in favor of System.IO.UTF8).

Write a character to the standard output device (same as hPutChar stdout).

Note: The implementation of putChar is not efficient.

Read a character from the standard input device (same as hGetChar stdin).

Note: The implementation of getChar is not efficient.

Computation hPutChar hdl ch writes the character ch to the file or channel managed by hdl. Characters may be buffered if buffering is enabled for hdl.

Note: The implementation of hPutChar is not efficient.

Computation hGetChar hdl reads a character from the file or channel managed by hdl, blocking until a character is available.

Note: The implementation of hGetChar is not efficient.

Computation hLookAhead hdl returns the next character from the handle without removing it from the input buffer, blocking until a character is available.

Note: hLookAhead is not implemented; it halts with a run-time error.

Computation hPrint hdl t writes the UTF8 string representation of t to the file or channel managed by hdl and appends a newline (same as hPutStrLn hdl . show t).

Note: hPrint has the same behaviour as System.IO.hPrint because show always produces an ASCII string.
