README for LeopardNSPreferredCharset.mailbundle

See
 http://code.google.com/p/leopard-preferred-mail-charset-fix/
for informations not mentioned in this file.

== Prerequisites
This plugin is Only for Mail.app on Leopard.

== How to install
Be sure Mail.app is not running.

Copy Leopard LeopardNSPreferredCharset.mailbundle into one of directories
~/Library/Mail/Bundles/
 or
/Library/Mail/Bundles/.

Then enter commands in Terminal.app
(Launch /Application/Utilities/Terminal.app.)
 defaults write com.apple.mail EnableBundles -bool true
 defaults write com.apple.mail BundleCompatibilityVersion 3

Launch Mail.app. 
If you are succeeded in installation process, you will see a console message
 "PreferredCharset initialized.".
(Launch /Application/Utilities/Console.app, then select "Console Messages" in the left pain.)

Open a new message window of Mail.app, you will see a line like that in Console.app

    11/09/05 9:29:48 Mail[621] setPreferredEncoding: 0x8000100 

When you change "Text Encoding" from "Message" menu you will see like that:

    11/09/05 9:44:39 Mail[745] setPreferredEncoding: 0x201 

(This time I choose "Western (ISO Latin 1)")
This value is required to build an encoding customized version.

== Customization for your charset (encoding)
Make sure you installed Xcode on Leopard

Checkout the source code of this project by following instruction:
http://code.google.com/p/leopard-preferred-mail-charset-fix/source/checkout

Replace the value of your preferred encoding to "PreferredCharset.m"

    [self setPreferredEncoding: 0x8000100];  // UTF-8

Save the source file and build the project.

Copy newly built LeopardNSPreferredCharset.mailbundle into the place I described Installation section of this document.

Restart Mail.app and wish good luck for it.
