jpmobile

jpmobile: A Rails Plugin for Japanese Mobile Phones.

jpmobile absorbs

Chaotic Speciﬁcations of Japanese Mobile Phones.

Today,

I’m going to take you to the chaotic world.

By the way,

We have kinds of characters.

I’m so nervous We have kinds of characters. at San Fransisco!

We have lots of characters.

Not only characters,

But also encodings!

Major Encodings: Shift_JIS Windows ISO-2022-JP E-Mail EUC-JP traditional UNIX UTF-8 modern systems

UTF-8 is not the only option.

We’re still using these encodings as the situation demands.

Ruby 1.9 works nice with this situation.

For example,

1.8 require ‘kconv’ Kconv::kconv(" ", Kconv::JIS, # to Kconv::UTF8 # from ) #=> "e$B;%KZe(B" We must care about the encoding of “ ” 1.9 " ".encode("ISO-2022-JP") #=> "e$B;%KZe(B" Ruby cares about the encoding of “ ”

Now we’re happy!

... in most cases.

Do you know

Emoticon

E + Moji + Picture + Character

Emoji makes the situation worse.

We have three major mobile phone carriers in Japan.

They deﬁne their own emoticon charset.

>A DoCoMo au SoftBank >> (Japanese usually paint the sun red) ><

DoCoMo au SoftBank >> Unicode U+E63E U+E488 U+E04A SJIS F89F F660 $Gj JIS >< 7541 w/escape SJIS’ EB60

Regular Encodings x Emoticon Encodings

That’s not all.

Five sad stories:

Sometimes the corresponding emoticon is not available on the other carriers.

“Snow crystal” DoCoMo au N/A SoftBank N/A

Nuances may be lost during the translation.

The official tables are not complete. (e.g. emoticons of prior company name are hidden)

Assignments of Unicode private area are partially overlapping between two carriers.

Solution:

jpmobile

Automatically translate = B the emoticons. >A Eb ! B Rails >> jk App jpmobile

jpmobile supports GPS, session management, subscriber identiﬁcation, template switching, ...

Conclusion:

If you are asked to build a website for Japanese mobile phones,

Say “No.”

Or use jpmobile.

Future works:

Reimplement jpmobile on Ruby 1.9 m17n framework!

Thank you!

Questions: After the last speech. Thank you.
