Because the PT application already supports one Asian language (Japanese), adding Chinese and Korean is not an overwhelming task. The version of the application localized for Japan already addresses multibyte character sets and the need for input method editors (IMEs).
The following table lists the local conventions that are shared and those that are different among the Chinese, Japanese, and Korean languages.
