macOS Localization of Mac Applications

Hi,

I have created a application for storage and backup. I used English as native language and developed it. Now I want to make my application Internationalize by adding localization to my application. Everything is fine. But I am able to create localization only in 3 other languages apart from English. The other 3 languages are Japanese, French and German.

Procedure I am following is :
1. Select the "nib" and open the of the project (File->GetInfo)
2. Select "General" tab, and click "Add Localization" button on the bottom left.
3. Select the language from the list and click Add.

That's it.

I want to know How to add other languages like Spanish, Italian etc languages for localizing my application.

Regards,
Satya.

What about some language names in Chinese, Japanese or Korean (i don't know exactly what language it is).......I observed the names of different languages in preferences of mac.

As said in previous comment, I am using the language codes and localized my application. For testing purpose I changed my Mac books language to French. In my project I have a directory "fr.lproj" which is related to French language.
I am running my application from Terminal/Console.
I observed the following error:

CFPropertyListCreateFromXMLData(): plist parse failed; the data is not proper UTF-8. The file name for this data could be: /Users/johnny/Library/Preferences/com.rogueamoeba.audio_hijack_server.hermes.plist
The parser will retry as in 10.2, but the problem should be corrected in the plist.


After few seconds one more error message displayed.

CFPropertyListCreateFromXMLData(): plist parse failed; the data is not proper UTF-8. The file name for this data could be:
/Users/johnny/satyam/freshcode/exe/Applications/iFolder 3.app/Contents/Resources/fr.lproj/iFolderWindow.nib/keyedobjects.nib
The parser will retry as in 10.2, but the problem should be corrected in the plist.



I am not understanding what I have to change in plist file?

I found out the error.
All the localization files generated must be in UTF-8 format, where are my files are in some other format.

In Windows simple chinese is denoted as zh-CN, but on Mac it is zh_CN, why there is a change in language codes between windows and Mac.

They didn't mention the OSX version where I have to use UTF-16
Do I have to use UTF-16 irrespective of Mac OSX version ie whether it is Tiger or Leapord.

Thanks for your updates so that I can change my file format.
How on Mac, How can I change the file format? Which Application I can use to save the files in UTF-16 format?

Also, on 10.4.11 NSLocale's localIdentifier for simple chines is returning zh_Hans and Taiwan chinese it is zh_Hant
What are these language codes irrespective of zh_CN and zh_TW?
