errors when adding WebHelp to CVS

I'm getting errors when attempting to add a WebHelp project to CVS using "import module":

text/binary conflict:

\resource\resource.xml

\whxdata\synonym.xml

files contain escape characters (0x00-0x20, 0x80-0xFF):

<.fm file name>.htm

<.fm file name>.css

Any suggestions on RoboHelp settings to change?

Alternatively, in CVS, for the XML files I can force binary, text, Unicode, no keywords expansion, or ignore. No such options for the .htm and .css errors.

I know it's odd to put compiled WebHelp in CVS, it's just the easiest way to make it accessible to the build system.

RoboHTML 9, FrameMaker 10, Windows Pro 7, WinCVS 2.0.2.4
