SQL & PL/SQL

I expected sqlplus to work interactively with the following settings:
- Lucida Console font for command window
- chcp 65001 (UTF8-Windows-Codepage)
- set NLS_LANG=.AL32UTF8

But it turned out that
1) sqlplus apparently does not use WIN32-API function ReadConsoleW and WriteConsoleW (these wide char functions must be used instead of ReadFile and WriteFile for Console I/O)
2) cmd silently ignores all .cmd and .bat files with codepage set to 65001.

I fear that such a problem regarding a minority of command line freaks has low priority for Oracle and for Microsoft, so I wrote two small filters in C.

rconsu8 passes keyboard input to stdout, using ReadConsoleW
wconsu8 passes stdin to console, using WriteConsoleW
both set the UTF8-codepage 65001 and restore the previous codepage at exit.

Anybody interested?
(Yes, I know that I could use sqldeveloper.)

Sample session:
C:\>set NLS_LANG=.AL32UTF8
C:\>rconsu8 | sqlplus scott/tiger@DBUTF8 | wconsu8
