DBCS characters appear garbled when you run some PowerShell scripts in EMS in an Exchange Server 2013 environment

Symptoms

Assume that Microsoft Exchange Server 2013 is installed on a computer that is configured to use a display language that uses Double-Byte Character Set (DBCS) characters, such as Japanese. Then, you run one of the following scripts in Exchange Management Shell (EMS):

• Disable-AntimalwareScanning.ps1

• Enable-AntimalwareScanning.ps1

• FilterringConfigurationCommands.ps1

• StoreTSLibrary.ps1

• Update-MalwareFilteringServer.ps1

In this situation, the DBCS characters appear garbled. More specifically, the characters resemble the following:

�}���E�F�A�΍�G���W����X�V���ł��B����ɂ͐���������܂��B
DateTime ��ɍX�V���ꂽ�G���W����m�F���Ă��܂��B
Microsoft ��X�V���Ă��܂��B�ŏI�X�V: 1900/01/01 9:00:00

Cause

This issue occurs because the *.strings.psd1 files that correspond to the scripts use the American National Standards Institute (ANSI) format instead of the 16-bit Unicode Transformation Format (UTF-16).

Resolution

To resolve this issue, install the following cumulative update:

2892464 Description of Cumulative Update 3 for Exchange Server 2013

Workaround

To work around this issue, save the *.strings.psd1 files in the UTF-16 format in the language specific subfolders in the Scripts folder.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
