It's a wiki , fancy helping out? :)

The source for this (in master) is here:
https://git-wip-us.apache.org/repos/asf?p=couchdb.git;a=blob;f=src/couchdb/couch_httpd_db.erl;h=3d2d2c1f301b6c733bd2cf5949c9e63b4e11baa3;hb=refs/heads/master#l1320
In detail this means:
validate_attachment_name(Name) when is_list(Name) ->
validate_attachment_name(list_to_binary(Name));
Ignore, it's Erlang internals. We're just making sure we operate on a binary
rather than a list datatype.
validate_attachment_name(<<"_",_/binary>>) ->
throw({bad_request, <<"Attachment name can't start with '_'">>});
What you found, they can't start with an underscore.
validate_attachment_name(Name) ->
case couch_util:validate_utf8(Name) of
true -> Name;
false -> throw({bad_request, <<"Attachment name is not UTF-8
encoded">>})
end.
Finally, the name's gotta be UTF-8 encoded.
