RAW option dosen't work in case of Spring DSL URI

I'm using camel version 2.12.1.
i'm using http component with authentication and i'm trying to keep the
passwor as it is without any encoding.

below my URI:

<to
uri="http://blablabla?authMethod=Basic橪;authUsername=sabri橪;authPassword=RAW(sabri)"/>
this will end up with non xml valid.
1- I'm asking if it is a bug or RAW option it's only used for java
DSL.(nothing mentioned in the online documentation).
2- authMethod and authUsername parameters must be used the uri and can't be
part of the Message headers Exchange.HTTP_URI. (also nothing mentioned in
the online documentation).

Thanks for any help.
