Mac OS X 10.4: Japanese message doesn‘t appear correctly in web mail or on cell phone when sent from Mail

If you send a message from Mail in Mac OS X 10.4 that contains Japanese language characters, it may not appear correctly in web mail (email accessed from a webpage) or on some cell phones.

This can happen because Mail encodes Japanese language messages as UTF-8 by default when English is the primary language selected in International preferences.

To resolve this issue, use Terminal to switch from using UTF-8 encoding to ISO-2022-JP encoding:

1. Open the Terminal (/Applications/Utilities/).
2. Type the following command at the prompt:
   
   defaults write com.apple.mail NSPreferredMailCharset "ISO-2022-JP"
   
   
3. Press Return to execute the command.
4. Quit Terminal.
