File Names with "?" cause failures with recursive copies

File names that contain "?" cause runs to fail and reports that it can't find a file name by section before the ?, and seemingly drops the ? and anything after.

Example code:
<pre>
file

{ '/tmp/foo': ensure => directory, recurse => true, purge => true, force => true, owner => 'root', group => 'root', mode => '0644', source => "puppet:///modules/foobar/foo", }

</pre>

Example directory/file structure:
<pre>
├── foobar
│   └── files
│   └── foo
│   ├── a
│   ├── b
│   ├── c
│   └── test?moretest

</pre>

Error:
<pre>
Error: Could not set 'file' on ensure: Error 404 on SERVER: Not Found: Could not find file_content modules/foobar/foo/test
Error: Could not set 'file' on ensure: Error 404 on SERVER: Not Found: Could not find file_content modules/foobar/foo/test
Wrapped exception:
Error 404 on SERVER: Not Found: Could not find file_content modules/foobar/foo/test
Error: /File[/tmp/foo/test?moretest]/ensure: change from absent to file failed: Could not set 'file' on ensure: Error 404 on SERVER: Not Found: Could not find file_content modules/foobar/foo/test
</pre>
