--------------------------------+-------------------------------------------
From 6.6, GHC supports UTF-8 encoding in the source programs. GHC can
read UTF-8 files and convert them into Unicode characters. However, there
are no support to read/print them.
For example, we can compile the following program,
{{{
main = putStrLn "あ"
}}}
but we only get `B', the least 8bit of the character `あ' (U+3042).
Because of this incompleteness, we cannot print any non-ascii characters
without converting for the case of writing Haskell codes with UTF-8.
Although it is easy to write converting functions for this purpose, such
converting should be supported by the compiler.
IMHO, desired approach is similar to Hugs. In Hugs, when printing non-
ascii characters, it first converts the characters to UTF-8 octets and
then prints them. However, with binary-mode Handle, it just print
characters without convert. This behavior will be acceptable for many
haskell programmers.
