The client does the keyword substitution, yes. But it does so not
only when checking out or updating a working copy, but also when

So, if your Word file contains the string '$Id:foo$', and "Id" is in
this file's svn:keywords property, then the Subversion client will
transform '$Id:foo$' to '$Id$' before sending the file to the server,
thus likely corrupting it if it is a binary file. The data has been
changed before the file was sent to the repository, therefore there
is no way to retrieve the original from the repository. Therefore you
must not set svn:keywords on binary files, unless you restrict
yourself to the fixed-width keywords, which are meant to work fine in
binary files. Assuming strings like '$Id$' do not otherwise appear in
the file.
