I would suggest buying FreeHand MX for Traditional Chinese, with this APP you can work with English, TC, SC, and Korean.
If you don't want to purchase there is a trick. If you are working on a Mac make sure you install your language kits and have Asian fonts. Use illustrator to insert your strings. When you do this you first have to apply a Asian font. Then paste in your text. Once you have everything in, convert to outlines and save as an eps file. Make sure there is no font data because it can cause printing issues.
Then open the file in FreeHand and drag your strings in.
This is how I used to do it till my company bought MX for TC.
