CVS is mangling some text files

I just went to some lengths to import and update some code of mine into 
CVS.  This is on a Windows Vista machine.  CVS client 1.12.12 (client), 
1.12.13 (Ubuntu server).

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 gives the garbage stuff again.

The mangling appears as "Asian" characters on every second line of the 
text files.  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
  ...


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