<para>Most of the time the Windows console is used to run Cygwin applications.
|
||||
While terminal emulations like <command>xterm</command> or
|
||||
<command>mintty</command> have a distinct way to set the character set
|
||||
used for in- and output, the Windows console hasn't such a way, since it's
|
||||
not an application in its own right.</para>
|
||||
|
||||
<para>This problem is solved in Cygwin as follows. When the first Cygwin
|
||||
process is started in a Windows console (either explicitely from cmd.exe,
|
||||
or implicitly by, for instance, clicking on the Cygwin desktop icon, or
|
||||
running the Cygwin.bat file), the Console character set is determined by the
|
||||
setting of the aforementioned internationalization environment variables,
|
||||
the same way as described in <xref linkend="setup-locale-how"></xref>.
|
||||
</para>
|
||||
|
||||
<para>However, in contrast to the application's character set, which is
|
||||
determined by the <function>setlocale</function> call, the console
|
||||
character set stays fixed for all subsequent Cygwin processes started
|
||||
from this first Cygwin process in the console. So, for instance, if
|
||||
<envar>LANG</envar> was set to "en_US.UTF-8" when the first Cygwin process
|
||||
started, the console is a UTF-8 terminal for the entire Cygwin process
|
||||
tree started from this first Cygwin process.</para>
|
||||
|
||||
<para>You're asking "What is that good for? Why not switch the console
|
||||
character set with the applications requirements? After all, the
|
||||
application knows if it uses localization or not." That's true, but
|
||||
what if the non-localized application calls a remote application which
|
||||
itself is localized? This can happen with <command>ssh</command> or
|
||||
<command>rlogin</command>. Both commands don't have and don't need
|
||||
localization and they never call <function>setlocale</function>. This
|
||||
would have the unfortunate effect, that the console would run with the
|
||||
ASCII character set alone. Native characters printed from the remote
|
||||
application would not show up correctly on your local console.</para>
