For example, FileZilla misparses filenames containing CR (U+000D), such as "blamp \r$(curl noncombatant.org)" currently in the public directory of the test grid. It appears to treat the characters after the \r as a separate line (judging from the Message log when 'Edit menu | Settings... | Debug | Show raw directory listing' is checked).

I think we should be stripping out children with names containing characters below U+0020 when found in a directory, and rejecting attempts to create them. See also #731.

This would be consistent with David A. Wheeler's suggestionL: http://www.dwheeler.com/essays/fixing-unix-linux-filenames.html .
