File truncated at ^Z character in windows

[John Russell <jorussel@cisco.com>]

I just moved my all my emacs customization stuff to windows.
Everything seems to work ok except for one thing.

One of the files stops when it sees a ^Z character.

e.g.
Real file part on Linux
...
jde-run) ("[?^C ?^V ?^S]" . speedbar-frame-mode) ("[?^C ?^V ?^W]" . jde-help-symbol) ("[?^C ?^V ?^X]" . jde-show-superclass-source) ("[?^C ?^V ?^Y]" . jde-open-class-at-point) ("[?^C ?^V ?^Z]" . jde-import-find-and-import) ("[?^C ?^V ?e]"
...

File when copied over to Windows.

...jde-run) ("[?^C ?^V ?^S]" . speedbar-frame-mode) ("[?^C ?^V ?^W]" . jde-help-symbol) ("[?^C ?^V ?^X]" . jde-show-superclass-source) ("[?^C ?^V ?^Y]" . jde-open-class-at-point) ("[?^C ?^V ?


And that's it.  That's the end of the file.  Does anyone know what is
special about the ^Z character that makes the file end like that?

note: in this post, I have written ^Z using Shift-6 and Z, but in the
file it is actually one character.

Thanks for the help.
