Need to run legacy (code-page based) applications on your Windows XP or Server 2003, but don't want to change the system locale? Here's a new utility that saves you a reboot! The Microsoft AppLocale (or Application Locale) utility is a temporary solution to these limitations caused by non-Unicode applications running on the Unicode (UTF-16) based Windows XP. AppLocale detects the language of the legacy application and simulates a corresponding system locale for code-page to/from Unicode conversions.
The AppLocale utility allows users to run a legacy application without changing to the code-page/system locale needed by that particular application. AppLocale emulates the code-page required by that legacy application without changing the machine's system locale. This emulation is only applied to the application that has been chosen during the AppLocale configuration wizard.
