.NET CF r/w the Shift-JIS file

I have a WEC7 of Colibri iMX6.
I have developed an application using .NET CF.
However, it can not be a text file read / write of the Shift-JIS.

Dim enc As System.Text.Encoding = System.Text.Encoding.GetEncoding("Shift_JIS")

PlatformNotSupportedException occurs.

Please tell me if there is a better way.

Did you already try to install the additional fonts? You find some ressources and a how to on this Toradex Developer website.

Thank you to answer my question.

Yes. Additional fonts are installed. Registry is also configured. However, the application will output the exception. (PlatformNotSupportedException)

Is this, probably because does not contain a Japanese environment to WEC7 OS image?

How about “shift_jis” ?
