so, wcwidth is apple's responsibility, then no libre-software developer can do 
anything,
Am I right ?

How to report this problem to apple ? Or maybe is it already done ?


well, i don't think that apple will correct it in 10.6,

So, to work quietly, I think there is an other option :
ask bash to not display special characters on the interactive line (all what i 
type)

i think that 10.4 was configured so that, but i don't know how apple had 
configured bash
it displayed things like "\65\301" instead of "é" (i think)

it was not very nice for eyes, but at least there was no big bugs like 
described above :-)
