[Bug ada/43041] New: Default WCEM for opened files is always WCEM_Brackets instead of the -gnatW-specified encoding

[mmarx at wh2 dot tu-dresden dot de]

The GNAT Reference Manual (8.6) specifies: `The default encoding method for the
standard files, and for opened files for which no WCEM parameter is given in
the FORM string matches the wide character encoding specified for the main
program (the default being brackets encoding if no coding method was specified
with -gnatW).'

However, if an empty FORM string is given to Open or Create, the WCEM is always
set to brackets coding, regardless of the encoding method that has been
specified with -gnatW:

Set_WCEM (a-witeio.adb:1632):
`if Start = 0 then
  File.WC_Method := WCEM_Brackets;
else'


from `gcc -v':
