There's no need to "ASCII-fy" or uuencode unless the file being RCS'ed
itself contains nonprintable characters.  Here's an actual RCS file
of my .logout file (a toy example, however):

--- RCS/.logout,v ---
head     1.2;
access   ;
symbols  ;
locks    ; strict;
comment  @@;


1.2
date     88.07.02.12.45.09;  author mkhaw;  state Exp;
branches ;
next     1.1;

1.1
date     88.07.02.12.43.31;  author mkhaw;  state Exp;
branches ;
next     ;

text

# $Header$

# $Log$
@
--- END of RCS/.logout,v ---

The initial version of the file was:

--- .logout ---
# $Header$

# $Log$

clear
--- END of .logout ---

After checking in the initial version ("ci"), I changed the second comment
line to:

# replaced "Log" header with this comment

and checked the file back in.  You can see that the RCS file starts with
a bunch of administrivial lines, then the complete verbatim latest version,
then diff-like lines for the reverse-delta to the previous version(s).
