Not sure what is your probleam with tolower. Anyways you can
re-use your old tolower by converting utf8 to latin1, do
everything that you used to and then convert back to unicode.
eg. unicode -> latin1
a. {~ 3&u:@ucp 'utf8 or wide unicode'
do not worry latin1 cannot display correctly in J session so
long as you know its bit pattern is correct.
