1

Anybody knows how to solve that?

Check this:

u.lastname

=> "Guimar\303\243es"

puts u.lastname

Guimarães
=> nil

u.lastname.titlecase

=> "Guimar\303\243Es"

puts u.lastname.titlecase

GuimarãEs # ------------------> Check the E in capital, this is a bug
=> nil

case conversion functions do/will not support characters out of ASCII
range (A-Za-z). Tim Bray enlightened us.

Titlecase is a Rails-ism (and the usual policy here is that Rails
questions should go to Rails lists or #rubyonrails IRC channel), but you can try:

puts u.lastname.chars.titlecase

If you're going to use utf-8 you need at least to set $KCODE='u'

>> $KCODE='n'
>> puts "Guimar\303\243es".titlecase
GuimarãEs

>> $KCODE='u'
>> puts "Guimar\303\243es".titlecase
Guimarães
