(void) setlocale(LC_ALL, "");
It will be easiest way now to make national chars available
for all ctype-oriented programs at once by simple:
setenv LANG Your_National_Charset
Default case (without "LANG" environment
variable) will be fully ANSI compatible (got "C" locale).
If "LANG" variable present, extention becomes active.
Effect of this extention is great: in one time all ctype
oriented programs can accept/print national characters
without any touching source/binary code, it is big win, IMHO.
This method is fully compatible with ISO8859-* and russian koi8-r
too (in general -- with all 8-bit character sets). I think
it is very useful.
I got this idea from Xenix locale implementation.
This extention is even never compiled in, unless you set
setenv STARTUP_LOCALE
before rebuilding crt0.c or corresponding variable in /etc/make.conf
program. The idea was that these are 'alignment' crap, but the image
is 16byte-aligned without these. Location 0 still doesn't have a 0,
but who cares, binaries wil be built with page zero unmapped in the
near future.
