Not true. There are several ways you can deal with this:

* Load your modified file explicitly in your .emacs. This will override 
the built-in copy.  You can even byte-compile the modified copy and load 
*that* instead.
* You can even just redefine "file-truecopy()" in your .emacs to 
override the built-in definition of that one function (this is a giant 
hairball of a function, though, so this may not be good in the long run).

If you're doing the fix, instead of just hacking the list of illegal 
characters embedded in the body of the function, it would be nice to 
break out the list regular expression into a defvar outside the body, so 
that it can be setq'ed by anyone wanting to twiddle the chars. Better 
still, make it a configurable variable using defcustom..
