4. Technical Description

Solaris supports many legacy (non UTF-8) locales in the dtlogin
screen. This allows the users to login to legacy locales and launch
applications in them. There are plans to replace dtlogin with gdm
as the default display manager in Nevada.

When the shift to gdm happens, legacy locales will be removed from the
login creen. Since future Solaris plans are to move away from the
legacy locales, gdm display manager won't be patched with legacy
locales in the login screen.

A mechanism which will allow users who still use legacy applications to
run them in a UTF-8 desktop is needed in such a scenario. (We will be
only removing support for legacy locales at the login screen, all the
supporting infrastructure pieces which allows users to run legacy
applications will remain).

The proposed locale launcher (/usr/bin/localelnchr) is such an
application which will allow the users to launch legacy locale
applications from a UTF-8 locale.

Locale environment variables, Input methods and fonts are the needed
components to the successful launch of an application from a desktop.
