For this release of Horizon Client for Windows Store, the documentation and user interface are available in English, Japanese, French, German, Simplified Chinese, Traditional Chinese, and Korean.
To input characters for languages other than English, you must configure the keyboard layout on the client device to match the keyboard layout in the remote desktop.
Limitations of International Keyboards
Several issues might occur with international keyboards. These issues are mostly related to double-byte characters, such as Japanese, Korean, or Chinese characters.
The solution is to use the local input buffer feature, available with Horizon Client 2.4 and later. To display the local input buffer, from the app commands at the bottom of the screen, tap the Input command. Text that you type into this text box is not sent to an application until you tap Send.
