libapache2-mod-encoding binary package in Ubuntu Mantic amd64

 This module improves non-ascii filename interoperability of
 Apache (and mod_dav).
 .
 It seems many WebDAV clients send filename in its platform-local
 encoding. But since mod_dav expects everything, even HTTP request
 line, to be in UTF-8, this causes an interoperability problem.
 .
 In the original author's opinion this is a future issue for
 specification (RFC?) to standardize encoding used in HTTP request-line
 and HTTP header, but life would be much easier if mod_dav (and others)
 can handle various encodings sent by clients, TODAY. This module does
 just that.
