On Windows, it's critically important to distinguish between text and
binary when creating a file, either by adding it or importing it.

Make sure it's really set in the repository and not just in your working
directory.  cvs log will show you the repository setting (keyword
substitution), cvs status will show you your working directory setting. 
The best thing to do is to use cvs admin to set the repository file
correctly and then do cvs up -A to synchronize the working file.

Windows has some strange ideas about what "text" means.  Those files are
likely Unicode encoded rather than ASCII -- Windows may consider that
text, but it's binary as far as CVS is concerned.  One way to find out
is to open the file in Notepad and then do File -> Save As: there's an
Encoding field that will tell you how the file is encoded.  Saving the
files as ASCII and then committing them should fix the problem.

You might want to consider using WinCVS as your client -- it does a very
good job of automatically detecting text vs. binary so you can fix up
the files as needed before committing them rather than trying to clean
up afterwards.
