CVS mangling files on Windows platform

[Harvey]

I recently went to some lengths to import and update some code of mine 
into CVS.  The CVS client is 1.12.12 on a Windows Vista machine.  The 
server (Ubuntu) is currently 1.12.13.  I think the server might have 
been 1.12.12a when I checked in some of the earlier versions of the 
files.  The protocol is pserver on a home LAN, port 2401.

There are about 90 files in the project.  When I checkout the project 
files, there are 4 files that are mangled and I can't seem to get them 
unmangled:

 xxx/res/MFCPCons.ico
 xxx/res/MFCPCons.rc2
 xxx/resource.h
 xxx/MFCPCons.rc

The .ico file is binary and correctly set up to be stored as binary in 
the repository.  The other 3 are text.  If I fix up the mangling and 
commit the files back to CVS, update leaves them alone but a checkout 
into a fresh directory (on the Windows Vista machine) gives the garbage 
stuff again.  I did a quick check on the Ubuntu machine and the files 
seem to have the correct content without corruption.

On the Vista machine, the mangling appears as "Asian" characters on 
every second line of the text files.  Every alternate second line shows 
up correctly.  As I compose this message, the strange characters all 
show up as "???" below.

For example, the file resource.h should be:


//{{NO_DEPENDENCIES}}
// Microsoft Visual C++ generated include file.
// Used by MFCPCons.rc
//
#define IDM_ABOUTBOX                    0x0010
#define IDD_ABOUTBOX                    100
#define IDS_ABOUTBOX                    101
#define IDD_MFCPCONS_DIALOG             102
#define IDR_MAINFRAME                   128
 ...

and what it appears as is:

//{{NO_DEPENDENCIES}}
??????????????????????????????????????????????????
// Used by MFCPCons.rc
?????
#define IDM_ABOUTBOX                    0x0010
??????????????????????????????????????????????
#define IDS_ABOUTBOX                    101
??????????????????????????????????????????????
#define IDR_MAINFRAME                   128
 ...


[On the Windows machine, the "???" characters above are Asian, all unique.]

Note that every second line has the correct content.  Every alternate 
second line is completely corrupted.

I still have the original files and can recreate from them if necessary.
