#3977: Support double-byte encodings (Chinese/Japanese/Korean) on Windows
---------------------------------+------------------------------------------
Reporter: shelarcy | Owner:
Type: feature request | Status: new
Priority: normal | Component: libraries/base
Version: 6.12.1 | Keywords:
Os: Windows | Testcase:
Architecture: Unknown/Multiple | Failure: Incorrect result at runtime
---------------------------------+------------------------------------------
localeEncoding uses the console code page for text file encoding/decoding
for single-byte encoding environment on Windows. But
GHC.IO.Encoding.CodePage.Table doesn't have double-byte encodings
(Chinese/Japanese/Korean), now. Its current state often causes problem on
double-byte encoding environment.

I know we can solve problem by using hSetEncoding with utf8 or othere
UTF-* encodings. But it's not good solution.
According to previous Windows patch, GHC.IO.Encoding.CodePage.Table
doesn't support double-byte encodings because Windows' shared library
support doesn't work.

{{{
Currently we do not support double-byte encodings
(Chinese/Japanese/Korean), since
including those codepages would increase the table size to 400KB. It will
be
straightforward to implement them once the work on library DLLs is
finished.
}}}
I think Windows' shared library support works now. Because #3879 is
closed.
So, how about add supporting double-byte encodings
(Chinese/Japanese/Korean) on Windows?
