[9fans] awk, not utf aware...

["Gorka Guardiola" <paurea@gmail.com>]

I think this has come up before, but I didn't found reply.
If I do in awk something like:

split($0, c, "");

c should be an array of Runes internally, UTF externally, but apparently,
it is not. Is it just broken?, is there a replacement?, is it just the
builtins or
is the whole awk broken?.

Example, freqpair

------
#!/bin/awk -f

{
	n = split($0, c , "");
	for(i=1; i<n; i++){
		pair=c[i] c[i+1]
		f[pair]++;
	}
}
END{
	for(h in f)
		printf("%d %s\n", f[h], h);
}

------

% echo abcd|freqpair
1 ab
1 cd
1 bc
% echo aícd|freqpair
1 cd
1 �c
1 í
1 a�


where the ? is a Peter face...

Thanks.
