Ldap filter problem

[Victor Zhestkov]

When I try to search using binary filter which contains \ac directly or this 
symbol, Filter->parse exclud this from
filter at all.
It's a shit, I can't use such filter 
(&(objectClass=inetOrgPerson)(networkAddress=1#\0a\00\01\ac)) it will be 
converted
through this function, exactly Filter->_escape and Filter->_unescape, without 
\ac
