Thank you, and yes, System.WCh_Cnv is internal used by Wide_Text_IO and
compiler.
Then, text read with Wide_Text_IO be JIS character code...because my
Windows comand prompt used Shift-JIS.
So I'd convert JIS character code to other code set(with iconv,
mbstowcs, etc). Raw JIS character code values are not popular in Japan.
Text data often encoded as Shift-JIS, EUC or UTF-8.
And other Ada packages assume Wide_String as Unicode. I think it's
natural, because C-functions assume wchar_t as Unicode.
If at all possible, I want take Wide_String as Unicode same as
C-runtime functions.
System.WCh_Cnv confound JIS character code with Unicode, it makes
troubles. Wide_Text_IO (and -gnatWs, -gantWe) are useless in fact,
because there is no what uses JIS character code as it is, conversion
is needed after all.
So, I want to know why System.WCh_Cnv takes JIS character code?
