What version of sort are you using? (run `sort --version')
What locale are you using? (run `locale')
The locale you use determines how bytes are ordered.
There are a few questions in the FAQ that should help you:

  http://www.gnu.org/software/fileutils/doc/faq/core-utils-faq.html

It works fine for me using the latest version and with
an appropriate locale settings:

  $ env LC_ALL=fr_FR sort -f < in
  à 2
  È 1
  è 3

If I use the default (C) locale, I get the
result that you didn't expect:

  $ sort -f < in
  È 1
  à 2
  è 3
