Conclusions from the svn:charset thread that Mark pointed out:
(1) This proposal should not gate on svn:charset since it isn't yet
recognized as official
(2) We should avoid the term encoding in documentation of this feature.
(3) There may be some bad interactions between ";charset=" in
svn:mime-type and auto-props, but this proposal does not raise new
issues, and those issues are a result of an error (possibly since
fixed?) in auto-props.
From the svn:charset thread:
Much of the early debate deals with svn:charset being non-standard and
non-approved. I tend to agree with Stefan, that this proposal
shouldn't gate on svn:charset being approved so I suggest tabling
One argument in favor of svn:charset, independently of the above, is
that unlike the current trick of appending "; charset=%s" to the MIME
type, it works with auto-props.
http://svn.haxx.se/dev/archive-2008-06/0983.shtml concludes the
problem is with auto-props. I tend to agree and even if auto-props
still have problems with spaces, the issue is separable from this
Mentions confusion between character set and encoding.
This is valid. My understanding is that
* a character set is a mapping from byte strings to code-point strings
* a content encoding is a mapping from byte strings to strings in some
other token set, so that they can be unpacked at the other end into a
The former assumes that the data being relayed is textual. The latter
assumes that the data being relayed is binary and that it is being
converted so that it fits into an envelope that uses a particular
The relevant standards already specify that the charset mime-type
parameter is the former, and so any documentation of this feature
should reference that and avoid using the term "encoding."
