Issue #1679 has been updated by ohookins.

Given mpalmer's test cases were run through puppet rather than puppetd my 
theory is currently that the stripping out of control characters must occur in 
the puppetmaster or at some point in tranmission to the client, perhaps in the 
encoding stage into or out of XML.

Bug #1679: Control characters can't be used within a file resource
http://projects.reductivelabs.com/issues/show/1679

Author: ohookins
Status: Accepted
Priority: Normal
Assigned to: community
Category: file
Target version: unplanned
Complexity: Unknown
Affected version: 0.24.5
Keywords: 


Our use case is thus: occasionally users will copy perl scripts over to our 
Linux machines from a Windows machine, unchanged, resulting in carriage return 
characters on the end of the line. Therefore the shebang might end up looking 
like this:

<pre>
#!/usr/bin/perl^M
</pre>

where the ^M is a carriage return character (you can get this in Vi by typing 
^V^M). To alleviate problems with these scripts we usually create a few links:
/usr/bin/perl^M -> /usr/bin/perl
/usr/local/bin/perl^M -> /usr/bin/perl

etc.

If you attempt to put the control character ^M into the manifest to create the 
link, it is ignored (or stripped out) by puppet and we end up over-writing 
/usr/bin/perl with an invalid link to itself.

<pre>
file { "/usr/bin/perl^M":
        ensure => "/usr/bin/perl";
}
</pre>

For the moment I've had to resort to execs to get the job done (which 
unfortunately still messes with puppet's debug output due to the ^M) but it 
would be nice if puppet could handle the control character natively.
