In mantis install workspace, the following files should be broken down into individual files for 9 locales plus English.
make/installer/bundles/windows/ishield7/jre/jre/ISString.idt (9 locales)
make/installer/bundles/windows/ishield7/sdk/sdk/ISString.idt (ja only?)

Currently, the ISString.idt file contains the localized strings for all locales. It is difficult to include strings with different encodings into one file without corrupting one or another. Also, it's difficult to maintain.
