Hirotaka Sato (Keio Univ) Nobuo Ogashiwa (Kyoai Gakuen College) + 2 abstract

n We examined several XMPP servers whether they support i18n or not

n I18n in XMPP is explained in internet-draft by peter n Internationalized Addresses in XMPP n draft-saintandre-xmpp-i18n-03 n (http://tools.ietf.org/id/draft-saintandre-xmpp-i18n-03.txt)

n We aimed to make sure it is working in real environment + 3 Interop test

Client Server n Many! n Hard to do this here…L

n Fairly easy

n We will do this here!

n We setup and tested several server at our own testing environment + 4 What means i18n for XMPP?

1. Get a international domain. n えっくすえむぴーぴー.net(xn--r8jau4b8b4fa8gr9cba.net)

2. Make a XMPP server

3. Connect from psi or adium n There seems no client which completely supports i18n + 9 Testing client

n Any client which fully capable of punycode? n PSI sometimes did not connect welll n Adium, oneteam, swift, iChat will not accept IDN… n Ended up with this→ + 10 Testing(cont.)

n 1st Test n Test whether client can connect with following setting

Username @ Domainname / resourcepart 1 Eng Eng Eng 2 Eng Jpn Eng 3 Eng Jpn Jpn 4 Jpn Jpn Eng 5 Jpn Jpn Jpn + 11 Testing(cont. 2)

n 2nd test

1. Set up MUC component then make sure it works fine when the room name is non-ascii.

2. Also, make sure it works when the nickname is non-ascii + 12 Overall result
