Okay Aznsound, I got Nero to burn a CD with Asian characters in the filenames.
Now, before I explain how I did it, let me present my disclaimer: I am comfortable enough with Japanese and Windows that I was willing to mess with the regional options on my system and run the risk of turning all my system menus into Japanese. I felt I would be able to restore them to English without any great difficulty if that did happen.
I did not run into any problems. The procedures I performed were not difficult, they did not
change my menus from English, and they were easily reversed. I honestly don't think there is any real risk of accidentally changing the language of the system menus. The dialogs I adjust in my procedures specifically state that they will not
change the language of the system menus, and even when I deliberately tried to change the system menus I could not. However, you still need to decide for yourself whether you wish to run even the small risk of switching the system interface from English to another language. In other words, if you try this and by some unforeseen and unlikely circumstances something actually does go wrong, leaving you with indecipherable and unusable Korean/Japanese/etc menus, I probably won't be able to help you.
Finally, I ran my test on a Windows 2000 box, not Windows XP. Since XP shares a fair amount of code with Windows 2000, I think it will work the same with XP, but I can not guarantee it.
Now, on to the procedures:
1. Open the "Regional Options" control panel applet (Start-> Settings-> Control Panel-> Regional Options
2. Select the "General" tab of the "Regional Options" window. The lower half of this tab has a box labeled "Language settings for the system". Press the "Set default..." button in the lower left corner to bring up the "Select System Locale" window as show here:
3. Select your desired locale. I only tested Japanese, because that is the only language in which I am interested. I assume Korean and Chinese will work the same way. However, be aware that there are multiple types of Chinese (traditional/simplified/etc) from which you can choose. If you also want to do Chinese and don't know what is appropriate for you, ask a Chinese friend.
4. Close the "Select System Locale" window by pressing the "OK" button, then switch to the "Input Locales" tab of the "Regional Options" window. Make sure that your default input locale is still English:
5. Close all the windows by pressing the "OK" buttons. You may be asked to insert the original OS CD-ROM so that some files can be copied, and the system will tell you it needs to reboot.
That is it. When your system comes up, you may notice a slightly different default system font, but it will still be in English.
You don't have to change anything with Nero, but now when you open it up you will see a new choice in the "Character Set" box of the "Write CD" dialog window. That choice is "Multibyte":
Make sure that you have both "Multibyte" and "Joliet" selected. You will now find that you can drag and drop files with Japanese (or Korean, if that is what you selected) characters, and that you can burn CDs with the same.
