Can proxy user id includes a '\'?

[Phil_yang]

We use a proxy to access Internet and everybody's user id includes a "\", such as kiddomain\pya. But my ubuntu does not work for apt when I input such a user id into /etc/apt/apt.conf. Could anybody help me out? Thanks!

Acquire::http::Proxy "http://kiddomain\pya:Lockman@192.168.0.6:8080"
Acquire::ftp::Proxy "http://kiddomain\pya:Lockman@192.168.0.6:8080 (http://kiddomain\pya:Lockman@192.168.0.6:8080)"
