We can command line debugger via "Windows" -> "Console" menu on HSDB. If the command shows error message in localized string (e.g. Japanese), it might garble. (see garbled.png on this issue)

Command line debugger and Debugger Console (WinDbg on Windows) will use Courier font on their console, but it does not show Japanese chars. I guess it would happen on CJK chars because monospaced font for Chinese, Japanese, Korean are different from Courier.
