Consider the following scenario:

  • You configure a Windows Embedded Compact 7-based OS design to create a run-time image that has a default locale value of Japanese (Japan) - (ja-JP).

  • In the image, you create an application that uses National/Regional Language Support (NLS) functions to process some Japanese characters. For example, you use the MultiByteToWideChar function to map a Japanese character string to a wide-character (Unicode) string.

  • You start the image and run the application.

In this scenario, the Japanese characters are corrupted.

Note This issue does not occur if you specify the default locale as Japanese - (ja) or as Japanese - (Japan, radicalstroke sort) - (ja-JP_radstr).


This issue occurs because of incorrect information in the Localeoptions.pbcxml file. When Japanese (Japan) - (ja-JP) is set as the default locale, the incorrect information in the Localeoptions.pbcxml file causes the corresponding registry value not to be set when you create the OS image.
